Abstract: Zirconium(IV)chloride (ZrCl4) catalyzed efficient one-pot synthesis of methylene-bis-β-amino/methylene-bis-β-acetamido ketones at room temperature has been described. In the presence of ZrCl4, the three-component Mannich-type reaction via a variety of in situ generated aldimines with various ketones, methylene-bis-methoxybenzaldehyde and aromatic amines in ethanol, led to the formation of methylene-bis-β-amino ketones and the four-component Mannich-type reaction of methylene-bis-methoxy­benzaldehyde with ketones, acetonitrile and acetyl chloride resulted in the corresponding methylene-bis-β-acetamido ketones in high to excellent yields. All the newly synthesized compounds have been characterized by their spectral and elemental analyses
