Abstract
Titanium tetrachloride rapidly anomerizes methyl 2, 3, 4, 6-tetra-O-benzyl-β-D- glucopyranoside in dichloromethane at 25° C. Evidence for the proposal that the benzyloxymethyl group on C-5 and the ring oxygen of the glucoside cooperate to prompt the reaction is described. The reagent anomerizes the interglycosidic linkage of several disaccharide derivatives.
