Sinularia scabra, is described. Hydroxycarboxylic acid, which is the key synthetic intermediate, was synthesized in a convergent manner by fragment coupling. The obtained hydroxycarboxylic acid was subjected to macrolactonization and subsequent transannular ring-closing metathesis (RCM) to furnish scabrolide F. The synthetic protocol can be extended to the total synthesis of other norcembranolides.
首次全合成 scabrolide F,一种从软珊瑚Sinularia scabra中分离出来的降雪松内酯。关键的合成中间体羟基
羧酸是通过片段偶联以收敛的方式合成的。将获得的羟基
羧酸进行大环内酯化和随后的跨环闭环复分解 (RCM) 以提供 scabrolide F。合成方案可以扩展到其他去甲松内酯的全合成。
