DEHYDRATIVE α-GLUCOSYLATION USING A MIXTURE OF p-NITROBENZENESULFONYL CHLORIDE, SILVER TRIFLUOROMETHANESULFONATE, N,N-DIMETHYLACETAMIDE, AND TRIETHYLAMINE

Abstract
Stereoselective synthesis of α-linked di- and trisaccharides is performed by the one-stage glucosylation using 2,3,4,6-tetra-O-benzyl-α-d-glucopyranose and a mixture of p-nitrobenzenesulfonyl chloride, silver trifluoromethanesulfonate, N,N-dimethylacetamide, and triethylamine in dichloromethane.
