straightforward, and general method for the synthesis of pyrido[1,2-a]pyrazine and pyrazino[1,2-a]quinoline derivatives via a one-pot three-component reaction between cyclic enamineones, aromatic aldehydes, and 1,3-dicarbonyl compound is reported. On our knowledge, this is the first reported one-pot multicomponent reaction for synthesis of pyrido[1,2-a]pyrazine and pyrazino[1,2-a]quinoline derivatives
