  摘要：

  The conjugate additions of the organocopper(I) reagents 22 and 27 to the enantiomerically homogeneous bicyclic enone 4 provided, after epimerization (NaOMe, MeOH) of the resultant product mixtures and appropriate chromatographic separations, the bicyclo[4.3.0]nonan-2-ones 24 and 28. Compounds 24 and 28 were readily converted, via two synthetic steps in each case, into,the sesquiterpenoids (-)-homalomenols B (2) and A (1), respectively.
