A synthetically useful reaction via NBS-mediated dinitrogen extrusion of N-aryl diazoacetamides under catalyst-free conditions is disclosed, which gives the 3-bromooxindoles in high to excellent yields with high selectivity via a non carbene process.
一种合成有用的反应通过NBS介导的催化剂自由条件下的N-芳基重氮乙酰胺的二氮化物挤出被揭示,该反应以高产率至极好产率高选择性地给出3-溴氧吲哚,通过非卡宾过程实现。
