An unexpected novel DMAP catalyzed Michael addition–elimination domino reaction between 2-naphthols and bromomaleimides has been reported. This protocol features metal-free catalysis and mild reaction conditions, which furnished 3-arylmaleimides in moderate to excellent yields (25–89% yields).
据报道,出乎意料的新型DMAP催化了2-萘酚和溴代马来酰亚胺之间的迈克尔加成-消除多米诺反应。该方案具有无金属催化和温和的反应条件,可提供中等至极好的收率(25-89%收率)的3-芳基马来酰亚胺。
