carboxamides has been developed. The method consists of two steps: the conversion to acetoxypivalimides (≥90% yield) and their mild alkaline hydrolysis (70∼90% yield). No epimerization at the α-position of the acyl group took place in the process. The amine part of the original amides can be recovered in good yield.
已经开发了一种有效且通用的水解N-单取代羧酰胺的方法。该方法包括两个步骤:转化为乙酰氧基新戊酰亚胺(≥90%产率)和温和的碱水解(70-90%产率)。在该过程中在酰基的α-位没有发生差向异构。可以以高收率回收原始酰胺的胺部分。
