• Formal Synthesis of (±)-Mitsugashiwalactone and (±)-Isodihydronepetalactone from Norborn-5-en-2-one Involving Shapiro Reaction
  作者：Meng-Yang Chang、Nein-Chen Ciang

  DOI：10.1002/jccs.199900005

  日期：1999.2

  AbstractA formal synthesis of (±)‐mitsugashiwalactone (1) and (±)‐isodihydro nepetalactone (2) was accomplished. Baeyer‐Villiger lactonization of ketone 9 followed by acidic treatment led to the rearranged lactone 8, which underwent a series of functional group transformations to give cyclopentanone derivatives 19 and 20. Shapiro reaction on 21 and 22 in the presence of excess dry ice gave lactones 5 and 6. Lactones 5 and 6 previously have been converted to mitsugashiwalactone (1) and isodihydronepetalactone (2), respectively.
