The CAN-catalyzed three-component between reaction between primary amines, β-dicarbonyl compounds and naphthoquinones or 2-bromonaphthoquinones afforded, respectively, 5-hydroxybenzo[g]indoles and benzo[f]indole-4,9-diones, the former of which were transformed into tetracyclic azepino[1,2-a]benzo[g]indole systems through a γ-alkylation/ring-closing metathesis sequence.
这 能够伯胺之间的反应之间催化的三组分, β-二羰基化合物和萘醌或2-溴萘醌分别提供了5-羟基苯并[ g ]吲哚和苯并[ f ]吲哚-4,9-二酮,它们的前者转化为四环氮杂[1,2- a ]苯并[ g ]吲哚 系统通过γ-烷基化/闭环复分解序列。
