  Total Synthesis of (−)-5,6-Dihydrocineromycin B

  摘要：

  An asymmetric total synthesis of (-)-5,6-dihydrocineromycin B has been accomplished in 13 steps from (-)-linalool O-triethylsilyl ether or 12 steps from geraniol. The present synthesis features (i) an intermolecular Wittig reaction involving an aldehyde possessing a ketophosphonate functionality and (ii) an intramolecular Horner-Wadsworth-Emmons olefination.
