  Synthesis of the proposed structure of queenslandon

  摘要：

  The proposed structure of the benzolactone queenslandon (6) was synthesized utilizing a triol containing building block prepared from D-ribose. While a ring-closing metathesis approach did not lead to the macrocycle, alkylation of a benzyl(phenyl)selane, elimination to generate the styrene double bond, followed by Mitsunobu macrolactonization proved to be successful. Spectral data suggest that the structure of queenslandon should be revised, probably to the C11 epimer. (C) 2009 Elsevier Ltd. All rights reserved.
