Abstract
The title compound, C(25)H(28)O(7), was prepared by the base-catalysed reaction of 3,4,5-trimethoxy-benzaldehyde with cyclo-penta-none. The mol-ecule has crystallographic twofold rotation symmetry and adopts an E-configuration about the central olefinic bonds. The two benzene rings and the central cyclo-penta-none ring are almost coplanar [dihedral angle = 4.7 (2)°].
