surprising rearrangement was observed during the reaction of securinine with tribromo-isocyanuric acid or 1,3-dibromo-5,5-dimethylhydantoin in methanol, yielding a stereoselective ring contraction norsecurinine derivative. Meanwhile two oxidation rearrangement products were also reported. Some preliminary discussions on the reactivity of securinine were conducted from these rearrangements; it is believed
研究了箭毒碱的溴化和氧化反应。在甲醇中水苏氨酸与三溴-异氰尿酸或1,3-二溴-5,5-二甲基乙内酰脲反应期间,观察到一个有趣且令人惊讶的重排,产生立体选择性环收缩的正苏尿碱衍生物。同时还报道了两种氧化重排产物。从这些重排进行了一些关于水仙碱反应性的初步讨论。据信它是由分子的碱性氮原子诱导的。
