(E)-3-(8-Benzyloxy-2,3-dihydro-1,4-benzodioxin-6-yl)-1-[2-hydroxy-4,6-bis(methoxymethoxy)phenyl]prop-2-en-1-one

In the title molecule, C28H28O9, the phenol and the benzene rings adjacent to the α,β-unsaturated ketone unit are inclined at 9.15 (13)° to each other. The terminal phenyl ring is oriented with respect to the phenol ring at a dihedral angle of 85.88 (13)°. In the crystal, the methylene C atoms of the dihydrodioxine ring are disordered over two sites with an occupancy ratio of 0.463 (18):0.537 (18), and both disordered components of the dihydrodioxine ring adopt twisted-chair conformations. An intramolecular O—H...O hydrogen bond and weak intermolecular C—H...O hydrogen bonds are present in the crystal structure.
