  Total Synthesis of Neolaulimalide and Isolaulimalide

  摘要：

  The first total syntheses of the potential antitumoral leads neolaulimalide (2) and isolaulimalide (3) have been achieved. Key steps in our convergent, fully stereocontrolled route are a Yamaguchi macrolactonization, a Julia-Lythgoe-Kocienski olefination, a Kulinkovich reaction, and a cyclopropyl-allyl rearrangement to install the exo-methylene group. Overall, we synthesized 2 in 21 linear steps (3% yield) and 3 in 24 steps (2% yield).
