Silver-catalyzed stereoselective synthesis of polysubstituted (Z)-1,2-dihydrobenzo[cd]indoles from 8-ethynylnaphthalen-1-amines is reported. In this protocol, a series of nitrogen-containing heterocyclic compounds were synthesized by silver-catalyzed α-addition of an alkyne bond with high selectivity and high yields. The synthesized polysubstituted 1,2-dihydrobenzo[cd]indoles could be easily converted to benzo[cd]indol-2(1H)-ones, and both 1,2-dihydrobenzo[cd]indoles and benzo[cd]indol- 2(1H)-ones are biological and pharmaceutical cores.

银催化的立体选择性环化成多取代的（Z）-1,2-二氢苯并[ cd ]吲哚

报道了由8-乙炔基萘-1-胺银催化的立体选择性合成多取代的（Z）-1,2-二氢苯并[ cd ]吲哚。在该方案中，通过银催化炔键的α加成反应，以高选择性和高收率合成了一系列含氮杂环化合物。合成的多取代的1,2-二氢苯并[ cd ]吲哚可以很容易地转化为苯并[ cd ] indol-2（1 H）-ones，1,2-二氢苯并[ cd ]吲哚和苯并[ cd ] indol-2 （1 H）-ones是生物学和药学上的核心。
