Abstract

An efficient silver-catalyzed, aniline mediated cascade hydroamination/cycloaddition of o- aminoaryl compounds including o-aminoaryl aldehydes, o-aminoaryl ketones with alkynes for the synthesis of 2-or 2, 4-substituted quinolines is reported. The reactions proceed with high regioselectivity to afford mono-or disubstituted quinoline derivatives in good to high yields using AgOTf as the catalyst in the air.
