C3-substituted indoles and carbazoles react with α-aryl-α-diazoesters under palladium catalysis to form α-(N-indolyl)-α-arylesters and α-(N-carbazolyl)-α-arylesters. The products result from insertion of a palladium-carbene ligand into the N?H bond of the aromatic N-heterocycles. Enantioselection was achieved using a chiral bis(oxazoline) ligand, in many cases with high enantioselectivity (up to 99 % ee). The method was applied to synthesize the core of a bioactive carbazole derivative in a concise manner.

An array of carbazoles (23 examples) can be synthesized from substituted biaryl azides at 60 °C using substoichio-metric quantities of Rh 2(O2CC3F7)4 or Rh 2(O2CC7H15)4.
Palladium-catalyzed direct arylation-based domino synthesis of annulated N-heterocycles using alkenyl or (hetero)aryl 1,2-dihalides
Ackermann, Lutz,Althammer, Andreas,Mayer, Peter
experimental part, p. 3493 - 3503 (2010/02/28)
A palladium-catalyzed reaction sequence consisting of an intermolecular amination and an intramolecular direct arylation enabled highly regioselective syntheses of functionalized indoles or carbazoles and proved to be amenable to the use of inexpensive 1,2dichloroarenes as electrophiles.
Domino N-H/C-H bond activation: Palladium-catalyzed synthesis of annulated heterocycles using dichloro(hetero)arenes

, p. 1627 - 1629 (2008/02/13)
(Chemical Equation Presented) One after the other: A novel palladium-catalyzed domino reaction consisting of an amination and a direct C-H bond arylation allows for a general synthesis of annulated heterocycles starting from readily available 1,2-dichloroarenes and primary as well as secondary anilines (see scheme; Cy = cyclohexyl). This is high-lighted by an efficient synthesis of the natural product murrayafoline A.
