NEW SYNTHETIC METHODS AND REAGENTS FOR COMPLEX CARBOHYDRATES .9. ARYLD-GLUCOPYRANOSIDES AND 1-ARYL-1-DEOXY-D-GLUCOPYRANOSES FROM 2,3,4,6-TETRA-O-BENZYL-ALPHA-D-GLUCOPYRANOSYL DIMETHYLPHOSPHINOTHIOATE

The reactions of 2,3,4,6-tetra-0-benzyl-alpha-D-glucopyranosyl dimethy lphosphinothioate and phenolic compounds gave the corresponding aryl a lpha-D-glucopyranosides predominantly in good yields, even when the tr imethylsiloxy derivatives of benzene, which are known to afford 1-aryl -1-deoxy-D-glucopyranoses by the conventional methods, were used as ac ceptors. On the other hands, 1-ary-1-deoxy-beta-D-glucopyranose was ob tained in good yield when 1,3,5-trimethoxybenzene was used as an accep tor.
