Abstract

Addition of indoles and pyrroles to activated quinolines and isoquinolines is achieved using 10 mol% of indium(III) chloride as a catalyst to produce 2-(1H-indol-3-yl)-1,2-dihydroquinolines and 1-(1H-indol-3-yl)-1,2-dihydroisoquinolines in excellent yields with high selectivity. This method is very useful for the functionalization of both indoles and quinolines in a one-pot operation.

Key words

aza-aromatics - indium reagents - indol-3-ylquinolines - pyrrol-2-ylquinolines
