In the title compound, C(21)H(19)ClO(3), the two cyclo-hexenone rings adopt half-chair conformations, whereas the pyran ring adopts a boat conformation. The 4-chloro-phenyl ring is almost perpendicular to the plane through the four C atoms of the pyran ring [dihedral angle = 87.97 (6)°]. In the crystal, weak C-H⋯O hydrogen bonds link the mol-ecules into a chain parallel to the a-axis.
