✦ Synopsis

The treatment of glycals with allyltrimethylsilane, trimethylsilyl cyanide and trimethylsilyl azide in the presence of catalytic amounts of Sc(OTf) 3 gave the corresponding 2,3-unsaturated allyl glycosides, glycosyl cyanides and glycosyl azides in excellent yields with high a-selectivity.
