Abstract SnCl 2-catalyzed three-component one-pot Mannich reaction of acetophenone or p- chloroacetophenone with different aromatic aldehydes and aromatic amines in ethanol at ambient temperature gave the corresponding β-aminocarbonyl compounds in good to excellent yields. Four new compounds are reported for the first time. Graphical abstract
