Series of 3-arylalkyl- or 3-alkylamino-4-(indol-1-yl)maleimides and bis(indol-1-yl)maleimides were synthesised. The cyclization of the 3-substituted 4-(indol-1-yl)maleimides under the action of acids resulted in the formation of diazepine[1,4] derivatives with indoline and maleimide nuclei annelated. These compounds readily produced the corresponding indolomaleimidodiazepines[1,4] after dehydrogenation.
合成了一系列 3-芳烷基或 3-烷基氨基-4-(吲哚-1-基)马来酰亚胺和双(吲哚-1-基)马来酰亚胺。在酸的作用下,3-取代的 4-(吲哚-1-基)马来酰亚胺环化,形成了吲哚啉和马来酰亚胺核环化的二氮杂卓[1,4]衍生物。这些化合物在脱氢后很容易生成相应的吲哚马来酰亚胺二氮杂卓[1,4]。
