  Second-generation total synthesis of (−)-diversifolin

  摘要：

  A second-generation total synthesis of (-)-diversifolin has been achieved by a more straightforward strategy. involving a highly stereochemistry-dependent 10-membered ring-closing metathesis and a stereoselective dihydroxylation/lactone transposition sequence. Compared to Our previous synthesis, the present synthesis is improved in the yield of the key intermediate 2 (20% in 12 steps from diol 8). (C) 2010 Elsevier Ltd. All rights reserved.
