Disclosed is a method for producing an optically active ester by highly selectively esterifying one enantiomer of a racemic carboxylic acid, while producing an optically active carboxylic acid which is the other enantiomer. An optically active ester is produced while producing an optically active carboxylic acid at the same time by reacting a racemic carboxylic acid with a specific alcohol or phenol derivative in the presence of benzoic anhydride or a derivative thereof and a catalyst such as tetramisole or benzotetramisole, thereby selectively esterifying one enantiomer of the racemic carboxylic acid.
本发明公开了一种生产光学活性酯的方法,该方法通过高选择性地酯化外消旋羧酸的一种对映体,同时生产出另一种对映体的光学活性羧酸。外消旋羧酸与特定的醇或苯酚衍生物在苯甲酸酐或其衍生物和催化剂(如四甲氧基苯甲醚或苯并四甲氧基苯甲醚)的存在下反应,从而选择性地酯化外消旋羧酸的一种对映体,在生产光学活性酯的同时生产光学活性羧酸。
