The enaminone framework is a versatile building block used in organic synthesis. Herein, a series of β-enaminones were synthesized in good to excellent yields from the reaction of various aliphatic and aromatic primary amines with 1,3-dicarbonyl compounds using common natural organic acids (lactic, malic, tartaric, citric and ascorbic acid) as green, eco-friendly and efficient catalysts under microwave irradiation and solvent-free conditions.
