  利用N-烯基取代的5-硫代吡咯烷基2-酮的光化学和自由基环化的方法来研究氮杂环化合物的方法

  摘要：

  已经研究了一系列环状的N-烯基取代的硫代酰亚胺的光化学反应。辐照N -3-甲基丁-3-烯基-5-硫代-吡咯烷酮-2-酮（16）导致分子内[2 + 2]环加成，从而产生高应变的硫杂环丁烷17，并根据其结构确定了结构X射线分析。用四氟硼酸二甲基（甲硫基）s处理环加合物17，以良好的收率得到2,5,6,7-四氢吡咯嗪-3-酮（20）。用阮内镍进一步还原20得到5,5-二甲基六氢吡咯烷-1-酮（21）。该反应顺序证明了将2 + 2光加合物转化为吡咯烷核生物碱核心骨架的便利性。密切相关的N-丁烯基噻吩并吡咯烷酮一（22）的光化学反应以略有不同的方式进行，并以68％的收率生产了7-巯基甲基四氢吡咯烷酮3-一（24）。与上述结果相反，在侧链上含有N-环烯基的硫代邻苯二甲酰亚胺基体系的辐照产生了由γ-氢从n-π*三重态激发态提取的产物。相关的N -3-烯基吡咯烷-2,5-二硫酮体系的光行为（62）也被研究并发现得到衍生自2
