At 153 °C feniculin (1) undergoes Claisen rearrangement to the 1,1-dimethylallylphenol (3), which is slowly converted into the 1,2-dimethylallylphenol (4); the products of abnormal Claisen rearrangement, phenol (4) and anisoxide (2), are formed at 185 °C. Anisoxide was shown by g.l.c. analysis to be absent in star anise oil and in the seeds of Illicium verum and Foeniculum vulgare, and is believed
Feniculin(1)在153°C经历Claisen重排成1,1-二甲基烯丙基苯酚(3),然后缓慢转化为1,2-二甲基烯丙基苯酚(4);在185°C时会形成异常的克莱森重排产物苯酚(4)和茴香氧化物(2)。Anisoxide通过GLC分析显示出在八角油和种子缺席八角和茴香,并且被认为已被作为茴香油的延长蒸馏的结果之前获得的。
