  An Improved Method for the Syntheses of β-Substituted Cyclohexenones

  摘要：

  An improved method for the preparation of beta-substituted cyclohexenones is reported. Conditions were defined to effectuate the key desulfonylation-deketalization step in a mild manner. Several cyclohexenones bearing acid and/or base sensitive beta-substituents were prepared by the modified method in moderate to good yields.
