An asymmetric o-methylbenzoyl tether for intramolecular glycosylations is prepared from o-methoxycarbonyl-benzylidene glucosamine by benzylation, saponification, condensation with phenyl 3,4,6-benzyl-1-thio-glucoside, and regioselective ring opening of the benzylidene moiety. Thus obtained prearranged glycoside affords the corresponding beta(1,4)-linked disaccharide as the major product.
