We present a new and straightforward one-pot process for the synthesis of 3-carbonyl-4-quinolone derivatives through highly efficient Cu-catalyzed aza-Michael addition of 2-aminobenzoates to β-substituted α,β-unsaturatedketones/cyclization/mild oxidation reactions. A broad range of new versatile 3-carbonyl-quinolin-4(1H)-ones is prepared from readily available chemicals under mild reaction conditions
