Disclosed is a selective ester production process of an alcoholic hydroxyl group, which proceeds under chemically mild conditions, while having adequate environmental suitability, operability and economical efficiency. Specifically disclosed is a process for producing an ester compound, which is characterized in that an alcohol and a carboxylic acid ester compound are reacted in the presence of a compound containing zinc element, thereby selectively acylating a hydroxyl group of the alcohol.

reducing agents is broadened through palladium-catalyzed methanolysis capable of reducing a wide variety of functional groups. Hence, borane mediated reduction of a benzamide followed by a tandem methanolysis/hydrogenolysis of the resulting borane–benzylamine adduct allows chemoselective removal of an N-benzoyl in the presence of an O-benzoyl.
