Abstract

The reaction of 5,6-(2,2-dimethyl­chromane)-2-hy­droxy-4-meth­oxy­acetophenone and 3,4-methlene­dioxy­benzaldehyde affords the title chalcone derivative, C22H22O6. 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 6.2 (1)° with respect to this unit, whereas the ring with the methyl­enedi­oxy substituent is aligned at 8.2 (1)°. The dihdral angle between the rings is 14.32 (7)°. The hy­droxy group engages in an intra­molecular hydrogen bond with the carbonyl O atom of the propenone unit, generating an S(5) ring.
