A new molecular rearrangement, the aza-Quasi-Favorskii rearrangement, has been developed for the construction of highly substituted aziridines. Electron-deficient O-sulfonyl oximes react readily with α,α-disubstituted acetophenone-derived enolates to furnish highly substituted aziridines via this unprecedented domino process. In-depth computational studies reveal an asynchronous yet concerted nitrenoid-type
一种新的分子重排,即氮杂-准法沃斯基重排,已被开发用于构建高度取代的氮丙啶。缺电子的O-磺酰肟很容易与 α,α-二取代苯乙酮衍生的烯醇化物反应,通过这种前所未有的多米诺骨牌过程提供高度取代的氮丙啶。深入的计算研究揭示了异步但一致的氮素型重排途径。
