The first asymmetric total synthesis of two naturally occurring antitumor pseudoplexaurol and 14-deoxycrassin were achieved via two convergent synthetic sequences featured a chiral pool protocol to implement C-1 stereogenic center and Ti(0)-mediated cyclization leading to cembrane ring.
通过两个收敛的合成序列实现了两种天然存在的抗肿瘤假水杨醇和 14-脱氧山素的首次不对称全合成,该合成序列采用手性池方案来实现 C-1 立体中心和 Ti(0) 介导的环化,形成西膜烷环。
