Highly beta stereoselective glycosylation by use of 1 o acetyl 2 6 anhydro 2 thioglycosyl donor for synthesis of 2 6 dideoxy beta glycosides

Highly beta stereoselective glycosylation by use of 1 o acetyl 2 6 anhydro 2 thioglycosyl donor for synthesis of 2 6 dideoxy beta glycosides

Tetrahedron Letters 33(11): 1491-1494

Gycosylations of the 1-O-acetyl-2,6-anhydro-2-thio sugar 3 with alcohols in the presence of several Lewis acids in CH2Cl2 proceeded smoothly to give the corresponding .beta.-O-glycosides with high stereocontrol in high yields, and the selectivity of the glycosylation was highly independent on Lewis acids.
