The acid-catalyzed Mannich reaction of acetophenones with benzaldehyde derivatives and aromatic amines gives 1,3-diaryl-3-(arylamino)propanones in high yield.
Recyclable heterogeneous Cu-nanoparticles efficiently catalyzed the one-pot three-componentMannichreaction of ketones, aromatic aldehydes and amines in methanol. This method provides a novel and improved method for obtaining β-amino carbonyl compounds in terms of good yield with little catalyst loading.

We have demonstrated the use of CeCl3· 7H2O as highlyefficient catalyst for one-potMannichreaction to afford β-amino carbonyl compounds in good to excellent yield within shorter period of reaction time. The process is mild, efficient, environmentally benign with the use of little amount of catalyst.
