Abstract

The data of a study on mixed aliphatic-aromatic anhydrides suggest that during the Yamaguchi esterification reaction, a symmetric aliphatic anhydride is produced in situ, which upon reaction with an alcohol yields the ester. A one-pot procedure for the regioselective synthesis of aliphatic esters is described using benzoyl or p-toluoyl chloride instead of the sterically hindered Yamaguchi acid chloride.
