Abstract: A direct alkoxycarbonylation/cyclization reaction is accomplished under visible light-induced photoredox catalysis. With this approach, a variety of ester-substituted indolo[2,1-a]isoquinolines are prepared in good to excellent yields. It is worth noting that this method not only… read more here.

Abstract: 2-(2-Bromoaryl)-1H-indoles are coupled and cyclized with 1,3-diketones by microwave irradiation in DMF in the presence of a catalytic amount of copper(I) iodide along with a base to afford the corresponding indolo[2,1-a]isoquinolines in moderate to good… read more here.
