One-pot three-componentMannich-typereaction of ketones, aldehydes and amines was efficiently catalyzed by liquid trifluoromethanesulfonic acid in water at ambient temperature. The high yield of corresponding β-amino ketones compounds were achieved. The proposed method is mild, green, simple and efficient.

affinity binding to androgen receptors, agonist and/or antagonist activities in both CV-1 and MDA-MB-453 transfection assays. A proliferation assay in LNCaP cells also exhibited this profile. A representative of these non-steroidal compounds (compound 21) was devoid of activity at other nuclear receptors (oestrogen, progesterone, glucocorticoid and mineralocorticoid receptors) in the CV-1 co-transfection

One-pot, three-component Mannich reactions of ketones, aldehydes and amines were efficiently catalyzed by AlPW12O40 in water at ambient temperature to give the corresponding beta-amino ketones in good to excellent yields. The method has the following merits: Firstly, Catalyst AlPW12O40 is non-corrosive and environmentally benign; Secondly, loading amount of catalyst is very low, less than 1 mol %; Thirdly, water as solvent is green and safe.

temperature to furnish β-amino ketones in good to excellent yields. The said protocol was further applied for the directsynthesis of β-amino esters, which are important precursors for the synthesis of β-amino acids. This protocol is potentially applicable for the development of a clean and environment-friendly strategy for the synthesis of β-amino ketones and found applications in the synthesis of potent biologically
