PROCESS FOR PRODUCING 1,2-ETHANEDIOL DERIVATIVES

摘要

A process for preparing a 1,2-ethanediol derivative in a high yield by reducing an alpha -hydroxy carboxylic acid ester derivative in a protic solvent or a hydrous aprotic polar solvent in the presence of a sodium boron hydride compound. A process for preparing a 1,2-ethanediol derivative in a high yield by esterifying an alpha -hydroxy carboxylic acid derivative to synthesize an alpha -hydroxy carboxylic acid ester derivative, and reducing this ester derivative in a protic solvent or a hydrous aprotic polar solvent in the presence of a sodium borohydride compound in the same reaction vessel.
