A convergent total synthesis of peloruside A () is described. The key strategic features are a diastereoselective lactonization to generate a C5-C9 valerolactone from the C-symmetric ketone , which comprises C1–C9 of , and a relay ring closing metathesis (RRCM) reaction to produce a dehydrovalerolactone , which embodies C13–C19. A new isomer of , the valerolactone -peloruside A (), was identified.
本文描述了海葵毒素A()的汇聚式全合成。关键的策略特点包括:通过非对映选择性内酯化反应,从C对称酮生成包含的C1–C9的C5-C9戊内酯,以及通过接力闭环复分解(RRCM)反应生成包含C13–C19的脱氢戊内酯。还鉴定出了的一种新异构体,即戊内酯 -海葵毒素A()。
