Cu-mediated regioselective, dehydrogenative homocoupling of indoles was developed using AgNO3 as the additive. The easily installed and removed N-pyrimidyl group exerted complete C2 regiocontrol via C–H activation. A series of indole substrates underwent cross-dehydrogenative-homocoupling. This work developed an effective approach for the synthesis of 2,2′-biindole core of a number of chemicals fundamentally

The palladium-catalyzed intramolecular oxidative coupling reaction of 1,1'-carbonyldiindoles was achieved by using Pd(OAc)(2) and Cu(OAc)(2), producing 1,1'-carbonyl-2,2'-biindolyls, which were then converted to tjipanazoles D and I

[Cp*IrCl2](2) catalyzes the cyclization of 2-ethynylanilines to 2,2'-biindoles via intramolecular hydroamination. A reaction pathway has been proposed on the basis of deuterium labeling experiments and computational studies.
