Abstract: In the title compound, C25H20O4, the dihydropyran rings adopt distorted sofa conformations. The molecule comprises two planar regions which form a dihedral angle of 62.56 (3)°. C-H interactions link the molecules to form centrosymmetric dimeric pairs. The dimers are interlinked along the  direction by C-HO hydrogen bonds.
