Abstract

Various acceptors including carbohydrates, amino acids, natural products, and hydroxylamine derivatives were coupled with 3,4,6-tri-O-acetyl-d-glucal in the presence of Cu(OTf)2 as catalyst. The protocol offers facile and efficient Ferrier glycosylation for the synthesis of 2,3-unsaturaed O-glycosides in good yields and high anomeric selectivity.
