Easy Access to Aryl‐ and Heteroaryl‐Annulated[a]carbazoles by the Indium‐Catalyzed Reaction of 2‐Arylindoles with Propargyl Ethers

Indoles and indium: An indium salt catalyzes the assembly of 2-arylindoles and propargyl ethers into diverse aryl- and heteroaryl-annulated[a]carbazoles in a highly regioselective manner, in which two different modes of carbon–carbon bond-forming reactions are successfully incorporated in one step (see scheme).
