intermediate 1,1-dimethylallylquinoline was trapped as its acetate which was cyclised to ifflaiamine with hydrobromic acid. An isomeric furanoquinoline alkaloid is shown to occur with ifflaiamine in Flindersia ifflaiana and the biogenesis of the two alkaloids is discussed.
1-甲基-4-(3-甲基丁-2-烯氧基)2-喹诺酮的克莱森重排主要导致异常反应,从而生成1,2-二甲基烯丙基喹啉及其线性和角环化产物。中间体1,1-二甲基烯丙基喹啉以其乙酸盐的形式被捕集,并被氢溴酸环化成艾来胺。异黄烷胺与异位呋喃喹啉生物碱已显示出在Flindersia ifflaiana中,并讨论了这两种生物碱的生物发生。
