Indoles undergo smooth addition to activated quinolines and isoquinolines in the presence of CeCl3·7H2O under extremely mild conditions to provide 2-(1H-3indolyl)-1,2-dihydroquinolines and isoquinolines in excellent yields with high selectivity. It is entirely a new protocol to functionalize both indoles and quinolines in a single-step operation.
