Abstract

Concise and efficient protecting-group-free total syntheses of chatenaytrienins-1, -3, -4 and muridienins-1–4 have been achieved. The key steps involve ring-closing metathesis (RCM) and C(sp)–C(sp3)-Sonogashira coupling. This work reports the first total syntheses of chatenaytrienin-3 and muridienins-1–4 in seven linear steps and high overall yields.
