title: Regioselective and stereoselective benzoylation of 2-N-protected 4,6-O-ketal derivatives of D-glucosamines with 1-(benzoyloxy)benzotriazole.
abstract: A highly regioelective and stereoselective benzoylation of the 2-N-protected 4,6-O-ketal derivatives of D-glucosamines with 1-(benzoyloxy)benzotriazole that affords the corresponding beta anomeric benzoates in excellent yields is described herein.
