Boric acid catalyzed chemoselective esterification of α- hydroxycarboxylic acids

Boric acid catalyzes the selective esterification of α- hydroxycarboxylic acids without causing significant esterification to occur with other carboxylic acids. The procedure is simple, high-yielding, and applicable to the esterification of α-hydroxy carboxylates in the presence of other carboxylic acids including β-hydroxyacids within the same molecule.
