The use of an N-acyloxazolidinone-protected S-adamantanyl thiosialoside allows the highly stereoselective, one-pot multicomponent synthesis of alpha-sialoside-based oligosaccharides.

see text]Because of the vast structural diversity encountered in the field of glycobiology, versatile methods for orthogonal oligosaccharide assembly are always of interest. Reported herein is the preparation of glycosyl chloride donors obtained by reaction of the corresponding thioglycoside precursors with chlorosulfonium chloride reagent 4. The crude chlorides thus obtained can be used directly in subsequent

The total chemical synthesis of a Forssman antigen analog is described. The pentasaccharide contains a functionalized tether which should facilitate future conjugation with immunogenic proteins. We found that the total synthesis can be efficiently achieved by following a convergent 2+3 strategy, and using N-Troc protected GalNAc thioglycoside as a donor. (C) 2011 Elsevier Ltd.

[EN] The present invention relates to thioglycosides and stereoisomeric forms, solvates, hydrates and/or pharmaceutically acceptable salts of these compounds, as well as pharmaceutical compositions containing at least one of these thioglycosides together with pharmaceutically acceptable carrier, excipient and/or diluents. Said thioglycosides have been identified as specific inhibitors of the sodium dependent glucose transporter 1 (SGLT1) and 2 (SGLT2), and are useful for the prophylaxis and/or treatment of hyperglycemia and hyperglycemia related diseases and conditions. [FR] La présente invention concerne des thioglycosides ainsi que des formes stéréoisomères, des solvates, des hydrates et/ou des sels de qualité pharmaceutique de ces composés, de même que des compositions pharmaceutiques contenant au moins l'un de ces thioglycosides en combinaison avec un vecteur, un excipient et/ou des diluants de qualité pharmaceutique. Il a été découvert que lesdits thioglycosides sont des inhibiteurs spécifiques des transporteurs SGLT1 (sodium dependent glucose transporter 1) et SGLT2 (sodium dependent glucose transporter 2), et pouvaient être employés dans le traitement prophylactique et/ou thérapeutique de l'hyperglycémie et des maladies et états pathologiques liés à l'hyperglycémie.

We report the first observation that a monosialyl residue is the essential structural element recognized by the enzyme CST-II; this has resulted in an attractive route to synthesize a series of α(2,8)-linked oligosialic acids and their thioanalogs in one step.
