Abstract
The corresponding acetylated and free 2-O- and 4-O-glucosyl derivative s of dianhydrohexoses Ib - VIIb and Ic - VIIc have been obtained by th e reactions of 2,3,4,6-tetra-O-acetyl-alpha-D-glucopyranosyl bromide ( IX) with 1,6:3,4- and 1,6:2,3-dianhydro-beta-D-hexopyranoses (Ia - VII a). Structure of the products and the effects of glycosylation upon ch emical shifts and conformations of the disaccharides prepared have bee n studied using H-1 and C-13 NMR spectra.
