Synthesis of 2-Indolyltetrahydroquinolines by Zinc (II)-Catalyzed Intramolecular Hydroarylation-Redox Cross-Dehydrogenative Coupling of N-Propargylanilines with Indoles
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 sp2 and one sp3) are activated in one shot and these hydrogen atoms are trapped by a propargylic triple bond in the molecule.
