Regioselective deprotection of p-methoxybenzyl ethers of furanose derivatives
摘要:
Reaction of per-p-methoxybenzylated hexofuranoses and pentofuranoses with either a catalytic amount of tin chloride dihydrate (SnCl2. 2H(2)O) or 0.5-10% solution of trifluoroacetic acid in dichloromethane afforded regioselectively the corresponding monosaccharide derivatives having a single free hydroxyl group at C(5) in good yields.
