title: Aldehyde as a Traceless Directing Group for Rh(III)-Catalyzed C-H Activation: A Facile Access to Diverse Indolo[1,2-a]quinolines.
abstract: The aldehyde group has been developed for the first time as a traceless directing group to promote regioselective Rh(III)-catalyzed C-H activation/cyclization of indolyl aldehydes with alkynes. This protocol streamlines access to a variety of appealing indolo[1,2-a]quinoline structures. As illustrative examples, a concise three-step synthesis of indolo[1,2-a]quinoline-based sensitizers is accomplished that exhibits the potential of C-H activation in the construction of organic optoelectronic materials.
