A novel class of non-steroidal progesterone receptorantagonists with aromatic β-amino-ketone scaffold have been synthesized and characterized with high binding affinity and great selectivity for the cognate receptors. Among them, compound 22 was shown to be the most potent progesterone receptorantagonist in cotransfection assay and a murine model of ligand-induced decidualization.

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.
