In studying the synthesis of tigogenyl β-O-cellobioside 1 via the trichloroacetimidate method of Schmidt, cesium carbonate was found to be an efficient reagent for the synthesis of peracetylated disaccharide α-trichloroacetimidates.Zinc bromide was superior to BF3*Et2O for coupling these disaccharide α-trichloroacetimidates with the steroid tigogenin.
