Abstract

A new Rh(III)-catalyzed oxidative bicyclization through C–H functionalization is presented. This reaction allows the selective assembly of diverse benzo[g]indoles from 4-arylbut-3-yn-1-amines and internal alkynes via a sequence of aromatic C(sp2)–H functionalization, cyclodimerization and nucleophilic cyclization.
