Abstract: The title compound, C₂₂H₂₁Cl₂NO, is a derivative of mono-carbonyl analogues of curcumin (MACs). The molecule has an E conformation for each of the olefinic bonds. The 1-propylpiperidin-4-one ring has a distorted chair conformation with the ring N and the C and O atoms of the carbonyl group deviating from the mean plane of the remaining four ring C atoms by 0.682 (2), -0.134 (3) and -0.340 (4) Å, respectively. The dihedral angle between the benzene rings is 26.5 (1)°. In the crystal, molecules are connected by weak C-HO and C-H [pi] interactions.
