herein is the mild and highly enantioselective synthesis of 2,3'-biindolyls via underexplored integration of C-Hactivation and alkyne cyclization using a unified chiral Rh(III) catalyst. The reaction proceeded via initial C-Hactivation followed by alkyne cyclization. A chiral rhodacyclic intermediate has been isolated from stoichiometric C-Hactivation, which offers direct mechanistic insight.
