✦ Synopsis

Direct Glycosylations with 1-Hydroxy Glycosyl Donors Using Trifluoromethanesulfonic Anhydride and Diphenyl Sulfoxide.

-A new method for glycosidic bond construction is described involving in situ activation of the anomeric hydroxyl. This one-step procedure is applicable directly to the glycosylation of a wide range of acceptors. The C-2 neighboring group effects the glycosylation stereochemistry. In the case of (XII) Ξ²-selectivity is observed exclusively. -(GARCIA, B. A.;
