The rearrangement of sulfamoyl azides under thermal conditions to form a C–C bond while breaking two C–N bonds is reported. Mechanistic study shows that this reaction goes through a Curtius-type rearrangement to form a 1,1-diazene, then which rearranges possibly through both a concerted rearrangement process and a stepwise radical process. This rearrangement could be used in the synthesis of complex
据报道,在热条件下,氨磺酰叠氮化物会重排形成一个C–C键,同时打破两个C–N键。机理研究表明,该反应经过库尔修斯式重排形成1,1-二氮杂苯,然后可能通过协同重排过程和逐步自由基过程进行重排。该重排可用于合成复杂的生物活性分子,例如固醇和胡椒碱衍生物。
