AN EFFICIENT METHOD FOR GLUCOSYLATION OF HYDROXY COMPOUNDS USING GLUCOPYRANOSYL FLUORIDE

Abstract Glucosides and disaccharides are prepared in good yields from 2,3,4,6-tetra-O-benzyl-β-d-glucopyranosyl fluoride and hydroxy compounds in the presence of stannous chloride and silver perchlorate. In most cases, α-glucosides are predominantly (α⁄β=80⁄20∼92⁄8) obtained.
