Abstract : The reaction of 5,6-(2,2-dimethylchromanyl)-2-hydroxy-4-methoxyacetophenone and 3,4-bis(methoxymethyloxy)benzaldehyde affords the intense orange title chalcone derivative, C25H30O8. The two benzene rings are connected through a - C(=O) - CH=CH - (propenone) unit, which is in an E conformation; the ring with the hydroxy substitutent is aligned at 19.5 (2)° with respect to this unit, whereas the ring with the methoxymethyloxy substituent is aligned at 9.3 (3)°. The dihedral angle between the rings is 19.38 (10)°. The hydroxy group engages in an intramolecular O - H⋯O hydrogen bond with the carbonyl O atom of the propenone unit, generating an S(5) ring.
