摘要
The title compound, C25H21ClO2, was synthesized via the three-component coupling of 4-chlorobenzaldehyde, 2-naphthol and 5,5-dimethylcyclohexane-1,3-dione. The pyran ring adopts a boat conformation, while the cyclohexenone ring is in an envelope conformation. The 4-chlorophenyl ring is almost perpendicular to the pyran ring [dihedral angle = 87.39 (1)degrees]. In the crystal, molecules are connected by intermolecular C-H center dot center dot center dot O hydrogen bonds.
