The title compound, C(30)H(32)FNO(2), was synthesized by the reaction of dimedone with 4-fluoro-benzaldehyde and p-toluidine in water. The dihydro-pyridine and both of the cyclo-hexenone rings are not planar and have flattened boat conformations. The dihedral angle between the planar aromatic rings is 15.33 (3)°. In the crystal structure, inter-molecular C-H⋯O hydrogen bonds link the mol-ecules into centrosymmetric dimers.
