The synthesis of novel pyrrolo[3,2-c]isoquinolines is investigated starting from 3-aminosuccinimides. Various known routes leading to 3-aminosuccinimides were tested but a new approach via nucleophilic addition of arylalkylamines on maleimide gave better results. The regioselectivity of the reduction of these compounds was shown to depend on the degree of substitution of the concerned 3-aminosuccinimide
从3-氨基琥珀酰亚胺开始研究新型吡咯并[3,2-c]异喹啉的合成。测试了导致3-氨基琥珀酰亚胺的各种已知途径,但是通过在马来酰亚胺上亲核加成芳基烷基胺的新方法给出了更好的结果。这些化合物还原的区域选择性显示出取决于所关注的3-氨基琥珀酰亚胺的取代度。羟基内酰胺在原位形成,然后转化为乙氧基内酰胺。后者在生成亚胺盐后,提供了目标吡咯并异喹啉和另一种新的杂环系统的另外两种衍生物:3,6-甲基-2,5-苯并重氮化合物。
