Abstract

The elusive epimerization process in the chiral butenolide moiety of Annonaceous acetogenins was examined under several sets of conditions commonly used for elimination leading to the alpha, beta-unsaturated lactone and the results provide practical guidance in choosing elimination conditions.

摘要

在几种常用于消除反应以生成α,β-不饱和内酯的条件下,研究了番荔枝科杀鱼菌素手性丁烯内酯部分难以捉摸的差向异构化过程,结果为选择消除条件提供了实际指导。
