The 1,3-dipolar-cycloadditions of two kind of isoquinolinium and carbolinium ylides with fumaric and maleic nitrile resulted in pyrroloisoquinoline and indolizino[8,7-b]indole derivatives, respectively, which are analogues of biologically active alkaloids. The cycloadditions were performed in good yield and proved to be stereoselective. The structure elucidation and complete 1H and 13C assignments
两种异喹啉鎓和咔啉鎓酰化物与富马酸和马来腈的1,3-偶极环加成分别产生吡咯并异喹啉和吲哚并[8,7- b ]吲哚衍生物,它们是生物活性生物碱的类似物。环加成反应产率高,证明是立体选择性的。通过各种一维和二维NMR实验的组合,已经获得了结构阐明以及完整的1 H和13 C赋值。
