  Synthesis of dendryphiellin C, a trinor-sesquiterpene from a marine source

  摘要：

  Enantioselective synthesis of dendryphiellin C, isolated from cultures of Dendryphiella sarina, has been achieved in a convergent way such as coupling of a C9-branched carboxylic acid 10 with a trinor-eremophilane alcohol 11. The latter was synthesized starting from a chiral building block, (1S,5S,6R)-5-hydroxybicyclo[4.1.0]heptan-2-one 16, which was originally prepared in this group using biochemical transformation as a key step. The synthesis was completed through 12 steps from 16 in overall 2.4% yield. (C) 1999 Elsevier Science Ltd. All rights reserved.
