(e)-3-[2h-1,3-benzodioxol -5-yl)-1-(7-hydroxy-5-methoxy-2,2-dimethylchroman-8-yl)prop-2-en-1-one

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...
