(E)-1-(2-Hydroxy-6-methoxyphenyl)-3-(2-methoxynaphthalen-1-yl)prop-2-en-1-one

Abstract

In the title compound, C21H18O4, the dihedral angle between the naphthelene ring system (r.m.s. deviation = 0.014 Å) and the benzene ring is 9.68 (1)°. The C atom of the methoxy group of the naphthalene ring system is almost coplanar with the ring [C—O—C—C = −2.0 (3)°], whereas the C atom of the methoxy group of the phenol ring is slightly twisted [C—O—C—C = 6.2 (3)°]. An intramolecular O—H...O hydrogen bond generates an S(6) ring motif.
