Abstract
The use of secondary amines and NXS (X = Cl, Br, I) enables an unprecedented copper-catalyzed oxidative aminohalogenation of electron-deficient maleimides. This simple and green multicomponent reaction offers late-stage modification of drug molecules and in situ formation of N-iodoamines for efficient alkene aminoiodination.
