The anhydro ring in a-methyl 2:3-anhydro-4:6-benzylidene-D-allopyranoside has been opened by the action of sodium benzylate to give 53% yield of a-methyl 2-benzyl-4:6-benzylidene-D-altropyranoside and 9% of a-methyl 3-benzyl-Q:6-benzylidene-D-glucopyranoside. After the removal of the benzylidene residue by acid hydrolysis, the position of attaclunent of the benzyl group is determined by periodate oxidation.
