| Abstract: | The three-component one-pot Mannich reaction of aromatic ketones, aromatic aldehydes and aromatic amines catalyzed by aluminium p-toluenesulfonate afforded the corresponding β-amino ketone derivatives efficiently at room temperature. The effects of different solvents and reaction conditions on the yields were investigated. After reaction, the catalyst could be easily recovered by phase separation and reused for many times without distinct decrease in its catalytic activity. The structures of products were characterized by IR, 1H NMR spectra and elemental analysis. |
