The acid-catalyzed Mannich reaction of acetophenones with benzaldehyde derivatives and aromatic amines gives 1,3-diaryl-3-(arylamino)propanones in high yield.
Highly stereoselective facile synthesis of β-amino carbonyl compounds via a Mannich-type reaction catalyzed by γ-Al<sub>2</sub>O<sub>3</sub>/MeSO<sub>3</sub>H (alumina/methanesulfonic acid: AMA) as a recyclable, efficient, and versatile heterogeneous catalyst

ketones, aromatic aldehydes, and aromaticamines catalyzed efficiently by γ-Al2O3/MeSO3H (alumina/methanesulfonic acid: AMA) as a heterogeneous catalyst, which were carried out in EtOH at ambient temperature to afford the corresponding β-amino ketones in good yields and high stereoselectivities in favor of the anti isomer, was described for the first time. It was found that this catalyst could be completely
