A straightforward two‐step synthesis of trans‐3,4‐disubstituted succinimides 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 heteroaryl halides, a variety of new analogues and derivatives of bioactive 3,4‐bisindolylmaleimides
描述了通过钯催化的Sonogashira反应和铁催化的双羰基化反应的简单的两步法合成反式-3,4-二取代的琥珀酰亚胺。原位氧化脱氢得到相应的3,4-二芳基马来酰亚胺。通过从容易获得的芳基和杂芳基卤化物开始,可以良好的收率和选择性获得各种新的具有生物活性的3,4-双吲哚基马来酰亚胺的类似物和衍生物。
