Editorial BoardSynOpen is an international, single-anonymized peer-reviewed, open access journal reporting current research results in chemical sciences in full paper, letter and review format.Target readershipSynOpen caters to a wide-range of chemists throughout industry and academia. We publish articles from across the chemistry portfolio, as long as synthesis or synthetic methods are one of the research focal points. People citing the work published in SynOpen come from all over the world and from a range of scientific disciplines.Subject scopeMain areas covered in SynOpen:Synthetic methodologiesAsymmetric synthesis and catalysisCatalytic methods for synthesisInorganic and organometallic synthesisNatural products synthesis and total synthesisMedicinal chemistry and drug designBiosynthesis and biocatalysisSynthetic photochemistrySynthetic electrochemistrySolid-state synthesisPolymer synthesisSupramolecular synthesis and self-assemblyMechanochemistryAutomation in synthesisComputational methods in synthesis and machine learningProcessing techniques and scalabilityRecycling processes and sustainable synthesisArticle TypesThe following article types are published in SynOpen:Original Papers cover original research which has not been previously published, except in the form of an abstract or preliminary communication.Letters are preliminary reports of new research results whose significance to the scientific community justifies rapid communication.Reviews and Short Reviews are critically evaluated recent developments and updates in a specific area of high interest to the readership providing a concise assessment of the current state of the art and an outlook on future developments.Graphical Reviews provide a concise overview of a current topic, highlighting historical background/origins of a research area and cutting-edge contributions along with the most recent developments. Text should be limited to a minimum. In preparing graphical reviews, authors should ask themselves how they would prepare lecture notes on the topic. For an example, see here. Authors wishing to submit a graphical review are requested to first contact Prof. Thierry Ollevier.Spotlights (up to 3 template-based pages, including tables and graphics) highlight the preparation and uses of selected reagents and methods in current research, so the bulk of references should be from the recent literature (2018 onward). It is a review-type article and therefore should not contain any unpublished res
