Abstract
The planar -CH=CHC(=O)- fragment (r.m.s. deviation = 0.074 Å) in the title compound, C18H18O5, connects the planar hydroxydimethoxyphenyl (r.m.s. deviation = 0.039 Å) and methoxylphenyl (r.m.s. deviation = 0.021 Å) parts. The central fragment forms a dihedral angle of 13.7 (1)° with the hydroxydimethoxyphenyl part and 32.0 (1)° with the methoxyphenyl part. The hydroxy group forms an intramolecular hydrogen bond to the carbonyl O atom.
