Abstract
In the title compound, C22H22O4, the two cyclohexenone rings adopt half-chair conformations, whereas the six-membered pyran ring adopts a flattened boat conformation, with the O and methine C atoms deviating from the plane of the other four atoms by 0.142 (2) and 0.287 (2)angstrom, respectively. In the crystal, weak C-H center dot center dot center dot O hydrogen bonds link molecules into chains running parallel to the a axis.
