Crystal structure of (2E)-1-(4-hydroxy-1-methyl-2-oxo-1,2-dihydroquinolin-3-yl)-3-(4-hydroxy-3-methoxyphenyl)prop-2-en-1-one

Crystal structure of (2E)-1-(4-hydroxy-1-methyl-2-oxo-1,2-dihydroquinolin-3-yl)-3-(4-hydroxy-3-methoxyphenyl)prop-2-en-1-one

In the title compound, C20H17NO5, the dihedral angle between the mean plane of the dihydroquinoline ring system (r.m.s. deviation = 0.003 Å) and the benzene ring is 1.83 (11)°. The almost planar conformation is a consequence of an intramolecular O—H...O hydrogen bond and the E configuration about th...
