  Studies directed toward the first total synthesis of acremodiol and acremonol

  摘要：

  Studies directed toward the synthesis of acremodiol and acremonol resulted in the synthesis of two macrodiolides 1, la, and 2 besides 3. The attempted synthesis of 1 and 2 confirmed that the absolute stereochemistry defined in the earlier report is incorrect. Compound I was synthesized by RCM-mediated macrocyclization. Attempted synthesis of 2 failed to give good yields in the cyclization, and la and 2 were synthesized by the Yamaguchi macrolactonization method. (C) 2009 Elsevier Ltd. All rights reserved.
