In the title compound, C(25)H(30)O(6), the two fused cyclo­hexa­none rings have envelope conformations, whereas the central pyran ring is roughly planar [mximum deviation = 0.045 (2) Å]. The pyran and benzene rings are almost perpendicular to each other, making a dihedral angle of 86.32 (2)°. In the...

description In the title compound, C(25)H(30)O(6), the two fused cyclo­hexa­none rings have envelope conformations, whereas the central pyran ring is roughly planar [mximum deviation = 0.045 (2) Å]. The pyran and benzene rings are almost perpendicular to each other, making a dihedral angle of 86.32 (2)°. In the crystal, molecules are linked via pairs of O—H⋯O hydrogen bonds, forming inversion dimers.
