Published: September 2015

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(sp(2))-H functionalization, cyclodimerization and nucleophilic cyclization.
