The glycosidations of silylated glycals and alcohols using a catalytic amount of BCl3 or BBr3 proceeded under mild conditions in a highly stereoselective fashion to afford the corresponding 2-deoxy-α-glycosides in high yields which were often found as the glycosidic components of several bioactive natural products.
