A catalytic oxidative carbonylation reaction was developed for the synthesis of polysubstituted maleimides from alkynes and amines with air as a green oxidant. This novel transformation proceeds in the presence of palladium chloride without the need for expensive ligands or additives and has a broad substrate scope affording a variety of maleimides in good to high yields.

An efficient Cu(OAc)2/Ag2CO3-cocatalyzed approach for the synthesis of 3-aminomaleimides and 3-amino-4-indolylmaleimides has been developed with satisfactory yields. A series of primary and secondary amines are compatible with this reaction. In addition, treatment of maleimides with primary amines using 1 equiv. of CuCl2leads to the formation of chloroamination products such as 3-amino-4-chloromaleimides by a radical-type mechanism.
