(E)-1-(2-Hy­droxy-4,6-di­meth­oxy­phen­yl)-3-(naph­thalen-1-yl)prop-2-en-1-one

In the title compound, C(21)H(18)O(4), the relative conformation of the C=C and C=O double bonds in the central enone group is s-cisoid; there is a trans configuration about the C=C bond. The dihedral angle formed by the naphthalene ring system and the benzene ring is 16.80 (2)°. The meth­oxy groups at the ortho and para positions of the benzene ring are tilted to the ring by 169.8 (1) and 174.5 (1)°, respectively. The hy­droxy group in the benzene ring participates in an intra­molecular O—H⋯O hydrogen bond. In the crystal, C—H⋯O inter­actions link mol­ecules into linear chains along the a-axis direction.
