PROCESS FOR MAKING ESTERS OF 2-ACETOXYALKANOIC ACIDS USING AN ALPHA-HYDROXYALKANOIC ACID ESTER AND AN ACETATE ESTER AS STARTING MATERIALS

摘要

2-Acetoxyalkanoic acid esters are made in a reaction of an α-hydroxyalkanoic acid ester and an acetate ester in the presence of a transesterification catalyst. Unlike previous methods for making 2-acetoxyalkanoic acid esters, this process proceeds in high yield and high selectivity to the desired product.
