摘要
In the title compound, C24H28O5, the two cyclohexene rings adopt envelope conformations, and the planes through the coplanar atoms makes dihedral angles of 82.86 (6) and 77.90 (6)degrees with the benzene ring. The two cyclohexene rings make a dihedral angle of 5.33 (6)degrees between their least-squares planes. The pyran ring adopts a flattened boat conformation. In the crystal packing, molecules are linked into two-dimensional networks parallel to the ab plane via O-H center dot center dot center dot O and C-H center dot center dot center dot O interactions.
