Abstract
Abstract Two α- D -linked disaccharides, 6- O -α- D -glucopyranosyl- D -galactose and 3- O -α- D -glucopyranosyl- D -galactose were synthesized by reaction of 2- O -benzyl-3,4,6-tri- O - p -nitrobenzoyl-α(or β- D -glucopyranosyl bromide with 1,2:3,4-di- O -isopropylidene-α- D -galactose and 4,6- O -ethylidene-1,2- O -isopropylidene-α- D -galactose, respectively, and subsequent removal of the protecting groups. No β- D -linked disaccharide was detected in the reaction mixture, irrespective of the anomeric configuration of the sugar halide used.
