An International Quarterly Journal of Heterocycles


Guidelines for Authors  


Aims and Scope

Heterocyclic Letters is a peer reviewed leading quarterly published International Journal devoted to the advancement of the science of synthetic heterocyclic chemistry. It seeks to publish articles on all phases of heterocyclic chemistry including natural products and inorganic ring systems.


Types of Contributions:


Manuscripts submitted to the Heterocyclic Letters should be Original Article or Review.


1.                  Original Article must either be of a current general interest or of great significance to a more specialized readership. It is peer reviewed and report details of studies that have not been published previously.


2.                  Reviewintroduces the reader to a particular area of an author’s research through a concise overview of a selected topic. The content should balance scope with depth. Reference to important work from others that is significant to the topic should be included. Review will have no “Experimental” section


The language of publication is English. The contents of papers are the sole responsibility of the authors and publication shall not involve the concurrence of the Editors or Publisher.

Editors reserve the right to adjust style to certain standards of uniformity. Original manuscripts shall be discarded two month after publication unless the Publisher is asked to return original material after use


Submission declaration and verification

Submission of an article implies that the work described has not been published previously, that it is not under consideration for publication elsewhere, that its publication is approved by all authors and tacitly or explicitly by the responsible authorities where the work was carried out, and that, if accepted, it will not be published elsewhere in the same form, in English or in any other language, including electronically without the written consent of the copyright-holder.


Disclosure and conflicts of interest

All authors should disclose in their manuscript any financial or other substantive conflict of interest that might be construed to influence the results or interpretation of their manuscript. All sources of financial support for the project should be disclosed.



Authors should submit the following items to the editor

Manuscript. You are strongly advised to embed the tables/figures/schemes in the relevant position in the manuscript file if possible. This will greatly assist the editorial-review process. Graphic files can also be submitted as separate, high resolution artwork files but please ensure to embed them in the manuscript file also.

Graphical abstract for the contents list (submitted as a separate document).

Cover letter:highlighting the novelty, significance, and urgency of the submitted work, which merits rapid publication and providing details of other relevant information, e.g., submitted or in press manuscripts.


• Author(s) should also send a declaration (in a simple cover letter) stating that this work is original and is not published or submitted for publication elsewhere.

1.      The language of publication is English.

2.      Authors should first examine a current issue of Heterocyclic Letter for guidance with respect to format, style, and presentation.


3.      Nomenclature should be based on the systematic rules adopted by the IUPAC or Chemical Abstracts. It is the responsibility of the authors to provide correct nomenclature.




1.                  Preparations of Manuscripts


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. Authors are required to use the appropriate template for the preparation of a research paper or review. Manuscripts should be prepared using a modern word processing program, preferably MS Word. Manuscripts in PDF format CANNOT be accepted. It will be preferred, if the authors submit manuscript in CD using Microsoft Word 6.0 or higher version with two hard copies of the manuscript as well as should transfer manuscript by electronic device/e-mail. Author(s) should also send a declaration (in a simple cover letter) stating that this work is original and is not published or submitted for publication elsewhere.


2.                  Organization of the Manuscript


Manuscripts should be divided into: Title, Author’s Name, Author’s Address (es) Affiliations, corresponding authors address, Abstract, Keywords, Introduction, Results and Discussion, Experimental Section, Conclusion, Acknowledgements, References, Tables, Figures, Schemes, Images and Graphical Abstract for list of contents.


Text file format:For the all typesetting in page setup the margins on all side should be 1 inch, gutter: 0, gutter position: left and orientation portrait. The Paper should be A4, width: 8.27inch, height: 11.69inch, for page layout Section start: continuous, header and footer should be 0.5 inch. The font should be Times New Roman with 12 fonts and for paragraph all boxes should be justified and line spacing should be single. 2.1. Title: The title should be clear, concise, and informative and should not include abbreviations. It should be typed with words all in bold face capitals, centered on the width of the first page, single spaced, font 12 pt, Times New Roman.


2.1. Title:  The title should be clear, concise, and informative and should not include abbreviations. It should be typed with words all in bold face capitals, centered on the width of the first page, single spaced, font 12 pt, Times New Roman..


2.2. Authors(s): After 2 single spaces from the title, author’s names and addresses should be given on separate lines, typed single spaced centered on the width of the first page, the font should be 12 pt and it should be regular for authors and addresses in italics. The name of the author to whom correspondence should be marked with an asterisk as superscript


2.3. Abstract:After 2 single spaces from author address, a short abstract (50-100 words) describing results, methodology employed, conclusions etc., should be placed. It should be labeled as the abstract with the word “Abstract” in 12 pt, bold, justified and Abstract text should be 12 pt, normal, justified and single spaced.


2.4. Keywords:The Abstract should be followed four to six keywords. Keywords subheading: 12 pt, bold, colon, followed by keywords 12 pt, Times New Roman, left justified. There should be single spaces before the next heading


2.5. Illustrations:Diagrams, graphs, spectra, photographs, and any other Figures should all be considered illustrations. Both line drawing and photographs should be used sparingly. All illustrations must be numbered in sequence using Arabic numbers as they appear, i.e. Figure 1 etc., and together with a caption appearing separately below each illustration. Authors should make clear any symbols (e.g. Greek characters, vectors, etc.) which may be confused with ordinary letters or characters. Figures should be included within the body of the manuscript close to the relevant text, but at the end of a paragraph. Authors should also send all figures at a minimum of 300 dpi resolution


2.6. Tables:Each Table should be numbered consecutively with Arabic numerals and provided with a descriptive title, above the table. Styles and fonts should match those in the Text file format. Tables must be created using Word table format. Do not use Chem Draw, ISIS Draw or Tabs to create tables. Tables must be oriented portrait style on the page and must fit within the margins of a single page. Exceptionally large tables may be placed landscape on the page with the top of table at the left-hand margin. Tables should be inserted in the text close to the point where they are discussed.

2.8. Reference:These should be numbered consecutively throughout the text as they appear and should be superscripted. All compound number in text should be bold e.g., phenothiazines 7 can be prepared…. Abbreviations for journals should be those used in Chemical Abstract. Abbreviations for other terms should also be taken from Chemical Abstracts/ACS journal. Each reference should be typed single spaced and the numbering should be in small Roman Numerals. Some examples for journal and books references are given:
