Glycosyl trichloroacetimidates react smoothly in the presence of trimethylsilyl trifluoromethanesulfonate as a catalyst with a variety of alcohols and monosaccharides in [bmim]PF6 (1-butyl-3-methylimidazolium hexafluorophosphate) as a solvent to afford the corresponding glycosides or disaccharides.

alpha-D-Glucopyranose-1,2-cyclic sulfites (1a-c) have been prepared by reaction of a suitably protected glucose residue and thionyl diimidazole. Reaction of these compounds with alcohols in the presence of Yb(OTf)(3) or Ho(OTf)(3) stereoselectively affords beta-O-glycosides
