  A cross-metathesis approach to the stereocontrolled synthesis of the AB ring segment of ciguatoxin

  摘要：

  Synthesis of the AB ring segments of ciguatoxin is described. The present synthesis includes a Lewis acid mediated cyclization of allylstannane with aldehyde, cross-metathesis reaction introducing the side chain, and Grieco-Nishizawa dehydration on the A ring.
