First total synthesis and structural confirmation of fluvirucinine A2 via an iterative ring expansion strategy

Org Lett. 2010 May 7;12(9):2040-3. doi: 10.1021/ol100521v.

Abstract

The first asymmetric total synthesis of fluvirucinine A(2) has been accomplished. A key feature of the synthesis is an iterative lactam ring expansion to provide rapid access to the 14-membered lactam skeleton and three stereogenic centers. The excellent remote control of the three stereogenic centers relied on stereoselective amidoalkylation followed by an amide-enolate-induced aza-Claisen rearrangement. In addition, the structure of fluvirucinine A(2) has been completely elucidated by our total synthesis.
