Abstract
d-Glycals undergo smoothly allylic rearrangement with allyltrimethylsilane and trimethylsilyl cyanide in the presence of catalytic amount of bismuth triflate to afford the corresponding 2,3-unsaturated allyl glycosides and glycosyl cyanides in excellent yields with high α-selectivity.
Key words
bismuth reagents - glycals - pseudoglycals - C-glycosides
