Boric acid catalyzed chemoselective esterification of alpha-hydroxycarboxylic acids.

Todd A Houston1, Brendan L Wilkinson, Joanne T Blanchfield.   

Abstract

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