An efficient method for regioselective benzoylation of diols and polyols was developed. The benzoylation is catalyzed by only 0.2 equiv of benzoate anion in acetonitrile with the addition of a stoichiometric amount of benzoic anhydride under very mild condition, leading to high yields. Compared with all other methods, this method shows particular advantage in regioselective multiple benzoylation of polyols, and in avoiding the use of any metal-based catalysts and any amine bases, which is more environment-friendly.

Acylation of representative carbohydrate derivatives was accomplished with in situ generated 1-acyloxy-1H-benzotriazoles. The observed high regioselectivity, mild reaction conditions and convenient work-up make the presented one-pot procedure generally applicable and more advantageous than acylations with previously introduced reagents, including N-acylimidazoles.
