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].

The title compound, C10H5ClF2N2OS, was obtained by linking an amino heterocycle and a substituted benzoyl chloride. The dihedral angle between the two rings is 41.2 (2)° and the equalization of the amide C—N bond lengths reveals the existence of conjugation between the benzene ring and the thiazole unit. In the crystal, pairs of N—H...N hydrogen bonds link molecules into inversion dimers. Non-classical C—H...F and C—H...O hydrogen bonds stabilize the crystal structure.
