Wang, Min,Song, Zhi-Guo,Wan, Xin,Zhao, Suang
, p. 1205 - 1208 (2009)
SnCl2-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.

β-Anilinodihydrochalcones readily undergo oxidation α to the carbonyl group region in the presence of a catalytic amount of iodine in dimethyl sulfoxide at 130 °C in good yield. Oxidation of allyloxy-substituted β-anilinodihydrochalcones to β-anilinochalcones is a preferred reaction over deallylation.
SnCl45H2O-catalyzed synthesis of β-amino carbonyl compounds via a direct Mannich-type reaction

experimental part, p. 1 - 6 (2011/12/22)
An efficient three-component, one-pot synthesis of β-amino carbonyl compounds from aromatic ketones, aromatic aldehydes, and aromatic amines using tin tetrachloride at room temperature in ethanol is described. The advantages of the new method are good yields (62-96%), simple workup, and inexpensive catalyst. Copyright Taylor & Francis Group, LLC.
Aluminium nitrate as an efficient and reusable catalyst for the three components one-pot Mannich reaction: Synthesis of β-amino carbonyl compounds
Wang, Min,Liang, Yan,Song, Zhiguo
supporting information; experimental part, p. 1653 - 1656 (2011/02/21)
Three components one-pot Mannich reaction of aromatic ketones, aromatic aldehydes and aromatic amines has been efficiently catalysed by recyclable aluminium nitrate at ambient temperature to give various β-amino carbonyl compounds in high yields. By simple phase separation, aluminium nitrate could be recycled several times without distinct loss of activity.
