efficient method for the synthesis of C-4 position alkylated azocino[4,3-b]indole 13 and 18 is described. Reduction of compounds 5, 6, 7 and 8 yielded the corresponding alcohols. Compounds 5, 6, 7 and 8 were synthesized through several steps starting from 1. The resulting alcohols underwent acid catalyzed ring closure to give tetracyclic azocino[4,3-b]indole 9, 10, 11 and 12. Finally, compounds 9 and
描述了一种合成C-4位烷基化的偶氮基[4,3- b ]吲哚13和18的有效方法。化合物5、6、7和8的还原产生相应的醇。化合物5、6、7和8是从1开始经过几个步骤合成的。对所得的醇进行酸催化的闭环,得到四环的偶氮基[4,3- b ]吲哚9、10、11和12。最后,化合物9和17在C-4位烷基化为相应的产物13和18。化合物13和18的结构已经通过X射线单晶分析确认。
