starting material, which is converted to the epoxide with m-CPBA and submitted to an anhydrous lithium perchlorate catalyzed rearrangement to the corresponding ketone. Hydrolysis and thermolysis of the ketone afford karahanaenone in good yield. The catalyst can be recycled by simple dehydration and reused without affecting the yield for the rearrangement.
据报道,单萜环酮卡拉哈烯酮(化妆品、香水和害虫防治剂中的一种成分)的合成得到了改进。该合成以乙酸芳樟酯为起始原料,用m-CPBA将其转化为环氧化物,并经无水高氯酸锂催化重排生成相应的酮。酮的水解和热解以良好的产率提供卡拉哈烯酮。该催化剂可通过简单脱水回收并重复使用,不影响重排收率。
