Apicularen A (1) and related benzolactone acylenamines belong to a growing class of novel natural products possessing highly cytotoxic properties. The challenging structure of 1 includes a 10-membered macrolactone ring, a tetrahydropyran system, an o,m-substituted phenol and a doubly unsaturated acyl group attached on the side chain enamine functionality. The total synthesis of apicularen A described
Apicularen A(1)和相关的苯甲内酯酰亚胺胺属于一类新兴的具有高度细胞毒性的天然产物。1的具有挑战性的结构包括10元大环内酯环,四氢吡喃系统,邻,间位取代的苯酚和连接在侧链烯胺官能团上的双不饱和酰基。本文所述的apicularen A的总合成涉及与其提议的生物合成等效的策略,并且需要以烯丙基化和臭氧分解为特征的一次重复两步法,以一次通过一个乙酸酯单元生长分子的链。
