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.

摘要
硼酸可催化α-羟基羧酸的选择性酯化反应，而不会导致其他羧酸发生显著的酯化反应。该方法简单、产率高，适用于在其他羧酸（包括同一分子内的β-羟基酸）存在的情况下α-羟基羧酸盐的酯化反应。[反应：见正文]
