  Pauson−Khand Reaction of Optically Active 6,7-Bis(tert-butyldimethylsiloxy)non-1-en-8-ynes

  摘要：

  Treatment of(6S, 7S)-7-bis(tert-butyldimethylsiloxy)non-1-en-8-ynes with dicobalt octacarbonyl gave the corresponding cobalt complex. This complex was subsequently exposed to the Pauson-Khand conditions in the presence of a promoter such as cyclohexylamine, thioanisole, methyl isopropyl sulfide, and butyl methyl sulfide ending up with the stereoselective production of the (2S, 3S, 6S, 7S)-7-methylbicyclo[4.3.0]nonenone derivatives instead of the expected (2S, 3S, 7S)-bicyclo[5.3.0]decenone species.
