  Alternative Synthesis of 2-Hydroxy-3,5,5-trimethylcyclopent-2-en-1-one

  摘要：

  AbstractThe 2‐hydroxy‐3,5,5‐trimethylcyclopent‐2‐en‐1‐one (1) was synthesized in 42% yield by rearrangement of epoxy ketone 10 on treatment with BF3⋅Et2O under anhydrous conditions. Intermediate 10 was available from the known enone 8, either via direct epoxidation (60% H2O2, NaOH, MeOH; yield 50%), or via reduction to the corresponding allylic alcohol 14 (LiAlH4, THF), followed by epoxidation ([VO(acac)2], tBuOOH) and reoxidation under Swern conditions, in 37% total yield.
