Acid-mediated glycosylations of endo- and exo-glycals have been carried out in good to excellent yields, in which a mixture of two products is often obtained resulting from Ferrier rearrangement and protonation. The former reaction exclusively takes place

[reaction: see text] Owing to the driving force of the Ferrier-type rearrangement, the exo-glycals are highly reactive with various alcohols to afford glycosides and glycoconjugates with exclusive alpha-configuration. The resulting vinyl group in these gl

Direct O-glycosidations using the 1-C-alkyl-2,3,4,6-tetra-O-benzyl-hexopyranoses as the glycosyl donors were carried out with a catalytic amount (0.2 equiv.) of trimethylsilyl trifluoromethanesulfonate (TMSOTf). The glycosidations proceeded α-stereoselect
