Regioselective acetolysis of highly O-benzylated carbohydrates promoted by iodine or an iodine/silane combined reagent: Use of isopropenyl acetate as an alternative to acetic anhydride
Regioselective acetolytic de-O-benzylation of poly-O-benzylated sugars can be triggered by the activation of isopropenyl acetate (IPA) with either an iodine/silane combined reagent or iodine alone. Unlike other known acetolysis procedures, the protocols p
