Novel and convenient dehydrative glycosidations of 1-hydroxy glycosyl donors have been developed. Several O-benzylated 1-hydroxy sugars are effectively cross-coupled with a variety of alcohols to give the corresponding O-glycosides in high yields with good α-stereoselectivities by using the heteropoly acid, H4SiW12O40.
