A straightforward two-step synthesis of trans-3,4-disubstituted succin imides through a palladium-catalyzed Sonogashira reaction and an iron-catalyzed double carbonylation is described. In situ oxidative dehydrogenation gave the corresponding 3,4-diarylmaleimides. By starting from readily available aryl and hetgeroaryl halides, a variety of new analogues and derivatives of bioactive 3,4-bisindolylmaleimides are obtained in good yield and selectivity.
