Abstract
AbstractN‐benzoyl‐4‐dimethylaminopyridinium chloride [DMAPBz]+Cl− was efficiently employed for polybenzoylation of triols and tetrols without epimerization and elimination products. This Lewis base adduct has also been employed for regioselective monobenzoylation of polyols obtained from D‐pentoses. Further an eco‐friendly monobenzoylation of phenols, amines and alcohols was achieved in water as a solvent without using a base and chromatographic purification of the products. Chemoselective monobenzoylation and recovery of the DMAP is an added advantage of our protocol.
