A convergent synthesis of the macrolide core as the immediate precursor to amphidinolide H1 is described, which features a palladium-catalyzed Stille cross-coupling, a methyl ketone diastereoselective aldol reaction, a Mitsunobu esterification, and an intramolecular ring-closing metathesis (RCM) reaction to construct the 26-membered macrocycle as key steps.
unselective “chemist” when it comes to making the highly cytotoxic amphidinolide macrolides of the B/G/H series. To date, 16 different such compounds have been isolated, all of which could now be approached by a highly convergent and largely catalysis‐based route (see figure). This notion is exemplified by the total synthesis of five prototype members of this family.
在生产具有高细胞毒性的B / G / H系列安非他命类大环内酯类药物时,自然界是一个非选择性的“化学家”。迄今为止,已分离出16种不同的此类化合物,现在可以通过高度聚合且主要基于催化作用的途径来接近所有这些化合物(见图)。该族的五个原型成员的总合成就是这一概念的例证。
