maleimides with secondary amines and NXS (X = Cl, Br, I) was developed, in which the N–X bonds generated in situ were used as difunctionalized reagents. The distinctive features of this multicomponent reaction include a simple green catalytic system, a spectral substrate range, and the late-stage modification of drug molecules. Most importantly, this umpolung radical cascade strategy exploits the in situ
开发了前所未有的铜催化的缺电子马来酰亚胺与仲胺和NXS(X = Cl,Br,I)的铜催化氧化氨基卤化物,其中原位生成的N–X键用作双官能化试剂。这种多组分反应的显着特征包括简单的绿色催化系统,光谱底物范围以及药物分子的后期修饰。最重要的是,这种蛋白基自由基级联策略利用了能够有效进行烯烃氨基碘化的N-碘胺的原位形成。
