  Total synthesis of motualevic acids A–F, (E) and (Z)-antazirines

  摘要：

  Total synthesis of motualevic acids A-F and (E) & (Z) geometrical isomers of antazirines has been achieved from a commercially available starting material, 1,10-decanediol. The synthesis of motualevic acid E served as a common key intermediate for the synthesis of most of these natural products. The key steps involved in this synthesis were Wittig olefination, Corey-Fuchs reaction, Neber reaction, amide coupling. (C) 2014 Elsevier Ltd. All rights reserved.
