Regioselective Acylation of Carbohydrates with 1-Acyloxy-1H-benzotriazoles

Abstract
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.
