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 theEconfiguration about the central C=C bond. In the crystal structure, O—H...O hydrogen bonds generate chains of molecules along the [10-1] direction. These chains are linkedviaπ–π interactions [inter-centroid distances are in the range 3.6410 (16)–3.8663 (17) Å].
