| 摘 要： | 环烯并吡咯衍生物在ＥＩ和ＦＡＢ条件下，可以发生游离基引发的氢重排失去一个中性的烯酮型分子，生成３－羟基－２－甲酰乙酯环烯并吡咯，后者由于邻位效应，又失去一分子乙醇、ＣＯ及发生缩环和一系列吡咯环的裂解反应。一些环己烯并吡咯衍生物的离子可以发生ＲＤＡ反应。

| Abstract: | The fragmentation process of cycloolefino b pyrrole in EI MS and FAB MS have been studied. It was that hydrogen rearrangement by initiation of radical site and loss of ketenes,occur to form 2 ethyl formate 3 hydroxy cycloolefino b pyrrole ions,followed by loss of an ethanol by ortho effect,loss of CO,and reducing pyrrole ring formed by loss of CO or HCN.Furthermore Retro Diels Alder reaction occur for some of cyclohexeno b pyrrole derivatives. |
