Rings with a twist: The highly enantioselective construction of five‐membered spiroindolenines has been realized by the iridium‐catalyzed intramolecularallylicdearomatization of indoles. The stereospecific migration of these spiro cyclopentane‐1,3′‐indole products provides enantioenriched 2,3,4,9‐tetrahydro‐1H‐carbazoles.
