The reactions of 2,3,4,6-tetra-O-benzyl-α-d-glucopyranosyl dimethylphosphinothioate and phenolic compounds gave the corresponding aryl α-d-glucopyranosides predominantly in good yields, even when the trimethylsiloxy derivatives of benzene, which are known to afford 1-aryl-1-deoxy-d-glucopyranoses by the conventional methods, were used as acceptors. On the other hands, 1-ary-1-deoxy-β-d-glucopyranose was obtained in good yield when 1,3,5-trimethoxybenzene was used as an acceptor.

6-Tetra-O-benzyl-1-O-trifluoroacetyl-α-D-glucopyranose is shown to react smoothly with aryl ethers in the presence of a Lewis acid in dichloromethane at room temperature to afford C-D-glucosylarenes with highstereoselectivity and in very highyield
