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.
