AUTHOR ALERT
AUTHORS' ATTENTION IS DRAWN TO THE NEW STYLE FOR LISTING REFERENCES cited in manuscripts submitted. MPublishing, which provides publishing services to Arkivoc, is now a member of CrossRef, and consequently, DOIs (digital object identifiers) are being assigned to all Arkivoc papers that have been published. This should help to ensure maximum visibility of your work published in Arkivoc since this linking system is used by all major journals. Participation in the system requires that all references cited should include a DOI when one is available. We ask for your cooperation in using the new style to facilitate our work in assigning DOIs to references. It is not necessary for authors to provide DOIs. Please refer to the Arkivoc Instructions to Authors (Section 2.2.16) for full details of the format for reference citing and listing. Manuscripts that do not use the correct format will be returned to authors for revision prior to review.

1. Editorial Policy of Arkivoc

1.1 Manuscript requirements
It is the responsibility of the senior author to ensure that all named authors have made a significant contribution to the work described in the manuscript and that all authors have seen and approved the manuscript prior to submission.
The manuscript of a full paper must be based on original research by the authors and the work must not have been published previously either in print or electronic format (exception: dissertations).
Manuscripts should be submitted to Arkivoc on an exclusive basis and must not be under simultaneous consideration by another journal.
If reference is made to an unpublished paper (“submitted” or “in press”), a copy of that manuscript should be provided by the author with the submission.
Medicinal Chemistry. Arkivoc is an organic chemistry journal and does not publish papers that are primarily concerned with medicinal chemistry. The journal does publish manuscripts with some medicinal chemistry content if the synthetic chemistry is novel and of general interest to organic chemists. Biological test results, if included, should form only a minor part of the manuscript, and biological results that are particularly significant or promising are more suitable for a medicinal chemistry journal. The final decision to publish such papers resides with the editors.

1.2 Evaluation of manuscripts
Contributions will be evaluated initially by the Primary Review Committee. Manuscripts that fulfil the essential scientific and editorial requirements for publication in Arkivoc will be reviewed by two or more members of the Editorial Board of Referees who advise the Scientific Editors on the suitability for publication. Authors are requested to submit three suggestions for referees.
Manuscripts that are unsound or have inadequate characterization of new compounds will not be accepted.

1.3 Date of receipt
The "date of receipt" recorded in the published article will be the date when a complete submission that satisfies all the requirements of the Technical Editor is received in the editorial office.


2. Preparation of Manuscript, Supplementary Materials, and Graphical Abstract
(Please note that "Communications" are not published in Arkivoc)

2.1 Manuscript text
Because Arkivoc is published online and in a printed version, it is essential that the files for both versions are compatible. In order to achieve this, authors are required to use the appropriate template for the preparation of a paper, account, or review. If, for technical reasons, this is not possible, the following format must be strictly adhered to. Failure to comply will result in the paper being returned for amendments before further consideration. Authors should refer to the sample paper or review for precise details of layout and format. For guidance on grammar, and chemical-usage in the preparation of manuscripts authors are recommended to consult The ACS Style Guide, Coghill, A. M.; Garson, L. R. Eds.; 3rd Edn.; Oxford University Press, 2006 (ISBN-13; 978-0-8412-3999-9). In a case of conflict between these sources, follow usage in a recent Arkivoc paper on the website.

2.1.1 The language of publication is English.

2.1.2 Word processor
Manuscripts must be prepared using MS Word as a doc file.
Manuscripts in pdf format CANNOT be accepted.

2.1.3 Macros and bookmarks: manuscripts containing macros and bookmarks CANNOT be accepted.

2.1.4 Text file format
Page setup: page size: US Letter (8.5 by 11 in, 22 by 28 cm.); margins on all sides are 1 in (2.54 cm).
Line spacing: setting "at least 16 pt."
Font: Times New Roman.
Text: 12 pt, normal, justified (left and right).
Symbols: Special characters (Greek letters, accents, mathematical symbols) must belong to the Times New Roman character set, i.e. must belong to the "normal text" Font in the Symbol selection window.

2.2 Organization of the manuscripts

2.2.3 Title
The title should clearly describe the purpose of the paper and should not include abbreviations (16 pt, bold, centered; followed by one empty line). Only the first letter of the title and of proper names in the title (e.g., Lewis acid) should be capitalized.

2.2.4 Author's name(s)
Typically, the following should be provided for each author:
Given name, middle initial and surname (12 pt, bold, centered; followed by one empty line).
The name of the corresponding author should be marked with an asterisk (*). If authors are from different institutions their surnames should be labeled after the name with a lower case superscript letter referring to the authors' addresses.
Example:  Albert J. Jones,a Dalpat Patel,b and Arthur Otherb*
The senior author must have the agreement of all authors for their names to appear on the paper.

2.2.5 Author's address(es), corresponding author's e-mail address
The complete mailing address(es) of author(s) should include the name of the institutional affiliation, street or P.O. box number, city, postal code, and country (12 pt, italic, centered).
The address line should be followed by the e-mail address of the corresponding author (12 pt, italic, centered; with hyperlink; followed by one empty line).

2.2.6 If a Dedication is desired, it should appear after a one line space below the e-mail address (12 pt, bold, centered).

2.2.7 Abstract
All manuscripts must be accompanied by a written abstract, which should state the purpose of the research, the principal results and major conclusions. The use of numbers in the abstract identifying formulas or tables is discouraged because the abstract text should be comprehensible when read alone. A typical abstract should contain no more than 100 words.
Abstract: Heading: 12 pt, bold, justified. Abstract text (on next line): 12 pt, normal, justified; followed by one empty line.

2.2.8 Keywords: the Abstract should be followed four to six keywords.
Keywords subheading: 12 pt, bold, colon, followed by keywords (first one capitalized and separated by commas): 12 pt, Times New Roman, left justified. There should be two spaces before the next heading.

2.2.9 Headings font size and style, alignment:
Major section headings (Introduction, Results and Discussion, Experimental Section, References, etc.): 14 pt, bold, left justified. There should be two spaces between sections and one space between each section heading and the text. The first paragraph of the text after major headings should not be indented.
Section subheadings: 12 pt, bold, left justified. Text begins on the following line and should not be indented.
Paragraphs should be indented (recommended 0.25 in or 0.64 cm) except the first paragraph after a section heading. In the Experimental Section paragraphs should not be indented.

2.2.10 Reviews and Accounts - Table of Contents (ToC)
A ToC should appear above the Introduction for Reviews and Accounts. Headings in Reviews and Accounts should follow the hierarchy and style as indicated below. The Introduction should be numbered 1.
1. Primary Heading (12pt)
1.1 Secondary heading (12pt)
1.1.1 Tertiary heading. (12pt, run on)
2. Primary Heading

2.2.11 Introduction
An introductory paragraph or statement should be given, placing the work in the appropriate context and clearly stating the purpose and objectives of the research.

2.2.12 Results and Discussion
All significant results that need to be rationalized should be discussed in this section. Experimental details should be kept to a minimum and reiteration of information from Tables, Figures, and Schemes should be avoided.

2.2.13 Conclusions
A brief Conclusions section is desirable, but not essential.

2.2.14 Experimental Section
General. This section should contain a description of instruments (make and model), and any special procedures used. The sources of all commercially available chemicals along with the source of all combustion analytical data, or work done outside the authors’ institution should be given.

Synthetic procedures in the experimental section should be accompanied by a listing of the most important product characterization data. Each paragraph describing a synthetic experiment should give the product’s systematic (IUPAC) name and the structure number assigned to the compound in the discussion section. Use of standard abbreviations or unambiguous molecular formulas for reagents and solvents, and of structure numbers rather than chemical names to identify starting materials and intermediates, is encouraged. Reactant and reagent quantities should be given in both weight and molar units. Yields should represent weighed amounts of isolated and purified products, and should be reported as percentages. When flash chromatography is used for product purification, both the support and eluting solvent should be identified.

Abbreviations, acronyms, symbols, and physical constants. Common abbreviations, acronyms, and symbols may be used, but less common ones should be defined the first time they are used (see the ACS Style Guide). Usage within a paper should be consistent, e.g., either Ph or C6H5 for phenyl, not both. Note: Ph should not be used for C6H4. The symbols used for physical constants should be in italics (e.g. d, J, k, c, m/z), but the units for physical constants should not be italicized. Equal signs should be avoided in citing data, e.g. J 5.1 Hz not J = 5.1 Hz.

QSAR studies. Arkivoc considers only those QSAR papers that meet the following criteria: (i) the work must involve statistical treatment of results obtained from the authors’ laboratory (they must not be culled from the published literature) and (ii) the paper should include a practical (experimental) element, as appropriate to an organic chemistry journal.

Microwave reactors. Work conducted in microwave reactors must indicate whether sealed or open reaction vessels were used and must document the manufacturer and model of the reactor, the method of monitoring the reaction mixture temperature (external surface sensor or internal probe), and the temperature reached or maintained in each experiment. Please note that Arkivoc does not publish reports of studies conducted with domestic (kitchen) microwave ovens.

Compound characterization data. Arkivoc upholds high standards for compound characterization to ensure that compounds being added to the chemical literature have been correctly identified and could be synthesized in known yield and purity by the reported preparation, isolation, and purification methods. For all new compounds, evidence adequate to establish both identity and degree of purity (homogeneity) must be provided. Purity documentation must be provided for known compounds whose preparation by a new or improved method is reported. If, in the opinion of the Scientific Editor, new compounds have not been satisfactorily characterized, the paper will not be accepted.
For known compounds synthesized by published methods, the method of preparation, the literature data used to confirm the identity of the material, and the technique(s) used to determine purity should be reported. For known compounds prepared by new or modified synthetic reactions, the types of physical and spectroscopic data that were found to match cited literature data should be identified, and purity documentation (see below) should be provided. Listings of IR and NMR absorptions and MS peaks for known compounds should be included only if they do not duplicate published data.
Evidence for the identity of new compounds should include both 1H and 13C NMR data and either HRMS or elemental analysis data. A criterion of purity (see below) must also be provided with HRMS data.

Proton and carbon NMR resonance signals should be listed for each new compound; the solvent and instrument frequency should be identified. Carbon NMR peak shifts should be rounded off to the nearest 0.1 ppm. Hydrogen multiplicity (C, CH, CH2, CH3) information (APT) obtained from carbon DEPT or 2D spectra may be included with the carbon peak shifts, if available, but is not essential information. The J values for all signals described as ‘d’, ‘t’, etc., must be given. For an example of the format for reporting NMR data, see the model Experimental Section at the end of the Instructions to Authors.
For new compounds, either HRMS (resolution 0.001 m/z unit or better) or combustion elemental analysis data should be reported to support the molecular formula assignment. The reported data should include the molecular formulae on which the theoretical (Calcd) values are based.

HRMS molecular formulae and Calcd values should include any added atoms (usually H or Na). The ionization method should be reported and a criterion of purity provided. A Found value within 0.003 m/z unit of the Calcd value of a parent-derived ion (for molecular weights less than 500), together with other available data (including knowledge of the elements present in reactants and reagents) is usually adequate for uniquely determining a molecular formula.

Elemental analysis. Found values for carbon, hydrogen, and nitrogen (if present) should be within 0.4% of the Calcd values for the proposed formula. The inclusion of fractional molecules of solvent or water in the molecular formula to improve the fit of the data usually reflects incomplete purification of the sample. If the reported formula includes such a molecule, independent evidence for its presence (such as NMR peaks with appropriate chemical shifts) should be presented. The format for reporting CHN analyses can be found in the model Experimental Section at the end of the Instructions to Authors.

Specific rotation. Specific optical rotations should be reported for isolated natural products, enantiopure compounds, and enantioenriched isomer mixtures when sufficient sample is available. Specific rotations based on the equation [α] = (100.α)/(l.c) should be reported as unitless numbers as in the following example: [α]D20 -25 (c 1.9, CHCl3), where the concentration c is in g/l00 mL and the path length l is in decimeters. The units of the specific rotation, (deg.mL)/(g.dm), are implicit and should not be included with the reported value.

Melting point. A melting point range should be reported for every crystalline solid product, together with the solvent from which it was recrystallised, and a description of the material e.g. "yellow needles, mp 123-124 °C (from EtOH)". For non-crystalline materials, there should also be a description, e.g. "brown oil; colorless gum". Similarly for liquids, e.g. "colorless oil, bp 123 °C (120 mmHg)".

IR and MS. Only those IR absorptions diagnostic for major functional groups, and only those MS peaks used for structure assignment, should be included in the experimental section. Complete peak listings or copies of the spectra may be included in the supporting information. IR bands, when reported, should be indicated using an approximate scale of relative intensities (vs, s, m, w = very strong, strong, medium, weak). Significant MS peaks should be reported with their % intensity relative to the base peak of the spectrum.

Purity. If a Scientific Editor feels it necessary to ask for evidence for compound purity, that evidence should include one or more of the following:
1. A standard 1D proton NMR spectrum or proton-decoupled 13C NMR spectrum showing, at most, trace peaks not attributable to the assigned structure.
2. Combustion elemental analytical values for carbon and hydrogen (and nitrogen, if present) agreeing with calculated values within 0.4%.
3. Quantitative gas chromatographic analytical data for distilled or vacuum-transferred samples, or quantitative HPLC analytical data for materials isolated by column chromatography or separation from a solid support.
4. For known solid compounds, a narrow melting point range that is in close agreement with a cited literature value.

Spectra. Reproductions of spectra will be published in the results and discussion section only when concise numerical summaries are inadequate for the discussion. Papers dealing primarily with interpretation of spectra, and those in which band shape or fine structure needs to be illustrated, may qualify for this exception. When presentation of spectra is essential, only the pertinent sections, should be included, either in the text or in supplementary information.

Crystallographic data. Only data and graphics vital to the discussion should be included in the manuscript. If the data are used solely for confirming compound identity or stereochemistry, a statement in the results and discussion or experimental section that the assignment is supported by an X-ray crystallographic structure determination is usually sufficient, though a ball-and-stick drawing or thermal ellipsoid plot can be included if desired. Regardless of the level of detail of the discussion of the structure, a Crystallographic Information File (CIF) containing complete details of data collection, crystal and unit-cell parameters, structure solution and refinement, and tables of atomic coordinates and thermal parameters, bond lengths, bond angles, and torsion angles should be furnished as supporting information. Reflection intensity data (structure factor tables) should not be included. If more than one crystal structure is being reported, the CIF for each structure should be furnished as a separate file. CIFs should be saved in text-only (plain ASCII) format and should be assigned file names that identify the structure number used in the manuscript and that include a ".cif" (not ".txt") extension. Before being submitted, CIFs should be checked and corrected using the free checkCIF data-validation utility at http://journals.iucr.org/services/cif/checkcif.html All structures for which an X-ray determination is included must also be submitted to the Cambridge Crystallographic Data Base and the unique number assigned to the compound in the data base, must be quoted in the experimental description of the compound.

For combinatorial libraries of more than 20 compounds characterization data must be provided for at least 20 diverse members.

Other material including, for example, molecular modeling coordinates, modeling programs, instrument and circuit diagrams, graphical kinetic data, and non-essential spectroscopic (e.g. IR, NMR, MS and UV/visible) data or other instrumental (e.g. electrochemical or chromatographic) details should be submitted in a separate Supplementary Material File (see 2.5).

2.2.15 Acknowledgements (optional)

2.2.16 References (and Notes)
The number of references cited should be limited to 50 for research papers. Long reference lists should be avoided by selecting references carefully and citing reviews, or selecting recent papers which contain many pertinent citations, whenever possible. References may appear in the reference list followed by "and references cited therein" if appropriate. There is no limit to the number of references that may be cited in reviews and accounts. All references must be cited in the text in numerical order using superscripts (without brackets). No links between superscripts in the text and actual references in the Reference Section may be used. Authors are asked to assign a separate number to each reference cited (e.g. 1-5), groups of references may not be nested under one number (e.g. 1a-e). All references should be listed in the "References" section at the end of the paper in numerical order with no text between the reference number and the first author's surname (e.g. "3. Jones, A..." not "3. See also Jones, A..."). There must be one blank line between each reference listed. Brief notes may be used to cite manuscripts in preparation, unpublished observations and personal communications, but longer notes should appear in the Supplementary Material section. Reference to experimental procedures or data must not be included in the reference list. The Chem. Abstr. reference should be cited for less accessible literature (e.g., patents). Digital Object Identifier (DOI) numbers should be given for papers cited that have been published online but have yet to receive page numbers. Authors are responsible for obtaining written approval for all personal communications and sending a copy of the manuscript to those cited as authors of personal communications.

References cited should follow the style below:

2.2.17 Authors’ Biographies (only required for reviews and accounts)
Each author should provide a photograph (portrait style, size 2 x 1.5 inches) and a short professional biography at the end of the manuscript.

2.3 Tables
Each Table should be provided with a descriptive title, above the table, e.g. "Table 1. Synthesis of S-acylcysteines 7a-e". The title, together with the individual column headings, should make the Table, as far as possible, self-explanatory.
Tables should be numbered consecutively with Arabic numerals and must be created using Word table format. Tables should be created using Microsoft Word. Do NOT use ChemDraw, IsisDraw or Tabs to create tables. Tables created in ChemDraw/ ISIS Draw will be returned to the author for proper formatting.
Structures within Tables must be drawn using ChemDraw or ISISDraw. They must not be inserted as picture images (e.g., JPG) and manuscripts that do not comply with this requirement will be returned to the author for proper formatting. Tables must be oriented portrait style on the page and must fit within the margins of a single page. Larger tables will be published as Supplementary Material. Structure numbers should be used in tables rather than chemical structure graphics. Tables should be inserted in the text close to the point where they are discussed. When inserting tables, do not use the "text wrapping"around the table option.

Example:


2.4 Graphics

2.4.1 Schemes, equations, and structure blocks
Scheme: depicts a series of chemical transformations containing chemical structures.
Equation: illustrates a simpler transformation with a single reaction arrow.
Structure Block: a collection of one or more numbered structures.
All graphics appear in the text immediately following the paragraph in which they are first mentioned.

For preparation of Schemes, Equations, and Structure Blocks, CS ChemDraw is the recommended drawing program, but ISISDraw may also be used (other programs are not acceptable). Do not insert the Schemes, Equations, and Structure Blocks as picture images.

With ChemDraw or ISISDraw the following settings should be used:

Text font: Arial, 10 pt
Fixed length: 14.4 pt (0.508 cm, 0.2 in)
Bold width: 2.0 pt (0.071 cm, 0.0278 in)
Line width: 0.6 pt (0.021 cm, 0.0084 in)
Bond spacing: 18% of width
Hash spacing: 2.5 pt (0.088 cm, 0.0347 in)

Owing to the incomplete implementation of the MATH tag in some of the most popular browsers, efficient handling of mathematical equations is not possible. Therefore, authors should create their mathematical equations in a layout program of their choice and then save the equation as an image in jpg format.

Within Schemes, Equations, or Structure Blocks, individual structures may be numbered with boldface Arabic numerals and lower case letters, e.g. 32a, 32b.
Schemes or chemical equations must be cited in the text using Arabic numerals, e.g. Scheme 1, Equation 1 etc.

Captions should be presented separately from the Scheme and Equation.

Examples:



Scheme 1. Synthesis of the known azide 6 from bromide 5 and sodium azide.


log k = (-2.62 ± 0.40)σ - (1.69 ± 0.17)                        (1)


When inserting Schemes, Equations, and Structure Blocks; do not use the float over text option.


2.4.2 Figures
Diagrams, graphs, spectra, photographs, and any other illustrations should all be considered Figures.
Figures should be labeled sequentially with Arabic numerals as they appear, i.e. Figure 1 etc. together with a caption appearing separately below each Figure.
Figures should be included within the body of the manuscript close to the relevant text, but at the end of a paragraph.

Color art        300 dpi

Example:

Figure 1. Lowest energy conformations obtained for BP6 superimposed with the structure obtained experimentally by X-ray crystallography (yellow, C – grey, N – blue, O – red, P – violet, H – white.


2.5 Supplementary Materials (optional)
Supporting information such as extended Tables, spectra, etc. may be published as Supplementary Material at the discretion of the author or upon request by a referee or the Scientific Editor. Supplementary Material should have a title page containing the information containing the information below:
Title of the manuscript;
Author's name(s);
Author's address(es);
Table of Contents with the page numbers of all the data;
All pages must be numbered as S1...
Tables, graphics, figures should be numbered as Table S1 or Scheme S1, or Figure S1.

Readers will be able to access supporting information using the link "Supplementary Material" in the journal issue contents page.

2.6 Graphical Abstract
A graphical abstract must be supplied with each manuscript. This graphic, in conjunction with the manuscript title and the author's name(s), should give the reader an impression of the chemistry described in the paper. It is not intended to be a written abstract, should not be detailed, and is not intended to summarize the results. The structure blocks, equations and schemes included in the graphical abstract should be created in Chem Draw or ISIS Draw and formatted according to the instructions under (2.4.1). The Graphical Abstract must be prepared using the template provided.

Melting points were measured on an Electrothermal 9100 apparatus and and IR spectra were recorded on a Shimadzu IR-460 spectrometer. 1H, 13C, and 31P NMR spectra were recorded at 500.1, 125.8, and 202.4 MHz respectively on a Bruker DRX-500 Avance instrument with CDCl3 as solvent and TMS as internal standard. Mass spectra were recorded on a GCMS-QP5050A spectrometer operating at an ionization potential of 70 eV. Elemental analyses for C, H and N were obtained using a Heraeus CHN-O-Rapid analyzer. Activated acetylenic esters, phenanthridine, isoquinoline, succinimide, indole, 2-methylindole, 2-benzoxazolinone, 6-chloro- benzoxazolinone, carbazole, 3,6-dibromocarbazole, 1,3-dimethylbarbituric acid, acetylacetone and dibenzoylmethane were purchased from Fluka, (Buchs, Switzerland) and used without further purification.

General synthetic procedure, exemplified by ethyl (E)-3-(6-(2,5-dioxopyrrolidin-1-yl)phenanthridin-5(6H)-yl)acrylate (4a). A solution of ethyl propiolate (0.1 g, 1 mmol) in CH2Cl2 (5 mL) was added dropwise over 10 min. to a magnetically stirred solution of phenanthridine (0.18 g, 1 mmol) and succinimide (0.09 g, 1 mmol) in CH2Cl2 (10 mL) at -10 oC. After several hours stirring at ambient temperature, the reaction mixture solidified. Solvent was removed under reduced pressure, the brown residue washed with cold diethyl ether (2×5 mL) and recrystallized from a mixture of acetonitrile and acetone.
