2-Acetoxyalkanoic acid esters are made in a reaction of a 3,6-dialkyl-1,4-dioxane-2,5-dione or a poly(α-hydroxyalkanoic acid), an acetate ester and an alcohol or phenol 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.
2-乙酰氧基烷酸酯是通过在3,6-二烷基-1,4-二氧杂
环戊二酮或聚(α-羟基烷酸)、
醋酸酯和醇或
酚的反应中,在酯交换催化剂的存在下制备的。与以往制备2-乙酰氧基烷酸酯的方法不同,这个过程产率高,对所需产品选择性高。
