An intramolecular hydroarylation-redox cross-dehydrogenative coupling (CDC) of propargylic anilines with indoles proceeded in the presence of zinc(II) catalysts to give 2-indolyltetrahydroquinolines in good to high yields. Three C-H bonds (two sp2and one sp3) are activated in one shot and these hydrogen atoms are trapped by a propargylic triple bond in the molecule.

Zinc(ii)-catalyzed intramolecular hydroarylation-redox cross-dehydrogenative coupling of N-propargylanilines with two types of carbon pronucleophiles (nitromethane as a sp3 carbon pronucleophile and phenylacetylenes as sp carbon pronucleophiles) proceeded to give the 2-substituted tetrahydroquinolines in good yields with 100percent atomic utilization without any additional external oxidants.
