Abstract
When used in intramolecular glycosylation processes unsymmetrical isophthal oyl ester disaccharides display different stereochemical behaviour when com pared to the corresponding phthaloyl ester disaccharides. The isophthaloyl ester disaccharides consist of a glycosyl donor and an acceptor, and are co nveniently prepared by sequential coupling reactions of dialkylstannylene a cetals derived from carbohydrates with 3-(2-mercapto-benzothiazolylcarbonyl )-benzoyl chloride.
