An efficient and highly stereocontrolled convergent synthesis of fluvirucinine A1 is reported herein. In fluvirucinine A1 both C5–C13 and C1–C4 fragments were accessed from a common intermediate 6 derived from (S)-Roche ester in 15 and 7 steps, respectively. The key steps involve Evans asymmetric alkylation, Sharpless asymmetric epoxidation, amidation and a ring-closing metathesis reaction (RCM) for
本文报道了高效的和高度立体控制的氟维新碱A 1的收敛合成。在fluvirucinine A 1中,分别从15个步骤和7个步骤分别从衍生自(S)-Roche酯的常见中间体6中获得C 5 -C 13和C 1 -C 4片段。关键步骤包括Evans不对称烷基化,Sharpless不对称环氧化,酰胺化和用于大环化的闭环复分解反应(RCM)。
