The synthesis of a novel class of macrocyclic bis(indolylmaleimides) is reported. The key step involves the intermolecular connection of 2,2′-bridged indoles with 3,4-dibromo-2,5-dihydro-1H-2,5-pyrroledione (dibromomaleimide) derivatives. The bis(indolylmaleimides) afforded by this method were further processed by intramolecular nucleophilic substitution of the remaining bromo substituents forming
报道了一类新型的大环双(吲哚基马来酰亚胺)的合成。关键步骤涉及2,2'-桥吲哚与3,4-二溴-2,5-二氢-1 H -2,5-吡咯二酮(二溴马来酰亚胺)衍生物的分子间连接。通过该方法提供的双(吲哚基马来酰亚胺)进一步加工,通过分子内亲核取代其余的溴取代基,形成柔性的N-取代大环(9a-9j,10a-10e),并通过连接两个马来酰亚胺,形成半刚性大环(7a-7xx))。
