Abstract

o-Aminoaryl ketones undergo a smooth, mild and selective condensation with α-methylene ketones on the surface of silver heteropoly acid (Ag3PW12O40) to afford the corresponding polysubstituted quinolines in excellent yields. The catalyst can be recovered by simple filtration and can be recycled.
