  Total syntheses of the proposed structures of cuevaene A

  摘要：

  Two proposed structures of cuevaene A were synthesized and the NMR spectra of both structures are proved to be inconsistent with those of the natural product. The structure of cuevaene A is still unclear and needs to be revised. (C) 2010 Elsevier Ltd. All rights reserved.
