Bi(OTf)₃as Novel and Efficient Catalyst for the Stereoselective Synthesis of<i>C</i>-Pseudoglycals

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.
