Special Issue Information

Dear Colleagues,

Advances in glycobiology are made at an ever-increasing pace. This makes today an exciting time to carry out research in carbohydrate chemistry and biology. The rapid progress in the field is catalyzed by the development of new techniques—but also owes a lot to the many developments within the efficient, stereoselective total synthesis of oligosaccharides of high complexity. The advent of new methodologies for (chemoenzymatic) glycosylation, efficient strategies and recently also the use of supports that facilitate the automation of glycan assembly is rapidly pushing the field toward a new era of glycomics. Oligosaccharide synthesis remains a challenging area of research, where we are yet to see methodology of sufficient generality to be applicable to most, and certainly not all, targets. Nonetheless, the toolbox of conditions, glycosyl donors and strategies is increasing, and so is our understanding of the forces that govern reactivity and selectivity in glycosylation chemistry. The long-term goal for the field should be to enable routine access to all oligosaccharides required for biological research, as analytical standards, for development of drugs and vaccines, etc., even for non-experts. The present Special Issue aims at covering new synthetic methodologies in oligosaccharide synthesis, novel targets procured and additional understanding of reactivity in carbohydrate chemistry.

Manuscript Submission Information

Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Molecules is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2700 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.

Abstract
The synthesis of two protected tetrasaccharide pentenyl glycosides with diarabinan and digalactan branching related to the pectic polysaccharide rhamnogalacturonan I is reported. The strategy relies on the coupling of N-phenyl trifluoroacetimidate disaccharide donors to a common rhamnosyl acceptor. The resulting trisaccharide thioglycosides [...] Read more.
The synthesis of two protected tetrasaccharide pentenyl glycosides with diarabinan and digalactan branching related to the pectic polysaccharide rhamnogalacturonan I is reported. The strategy relies on the coupling of N-phenyl trifluoroacetimidate disaccharide donors to a common rhamnosyl acceptor. The resulting trisaccharide thioglycosides were finally coupled to an n-pentenyl galactoside acceptor to access the two protected branched tetrasaccharides. Full article
