α-Glucosylation of Phenols with Tetra-O-benzyl-α-d-glucose

Abstract
An α-glucosylation of phenols with 2,3,4,6-tetra-O-benzyl-α-d-glucopyranose is described. This uses a mixture of p-nitrobenzenesulfonyl chloride, silver trifluoro-methanesulfonate and triethylamine in dichloromethane in a two-stage treatment.
