In the title compound, C13H12O5, the mean plane of the 2H-chromene ring system (r.m.s deviation = 0.026 Å) forms a dihedral angle of 81.71 (6)° with the mean plane of ethyl 2-hydroxyacetate moiety (r.m.s deviation = 0.034 Å). In the crystal, C—H
O hydrogen bonds result in the formation of zigzag layers parallel to the bc plane.

In the title compound, C14H17N3O2, the mean plane of the 1,8-naphthyridine ring system (r.m.s deviation = 0.020 Å) forms a dihedral angle of 23.4 (1)° with the acetamide moiety (r.m.s deviation = 0.001 Å). The molecular structure is stabilized by an intramolecular O—HN hydrogen bond, which generates an S(5) ring motif. In the crystal, molecules are linked into inversion dimers by pairs of N—HO hydrogen bonds, generating 18-membered R22(18) ring motifs.

In the title compound, C32H26Cl2F2N2O2, the tetrahydropyridine ring adopts a distorted boat conformation. The chlorophenyl rings are inclined to one another by 55.2 (1)°, while for the fluorophenyl rings the dihedral angle is 80.7 (1)°. The amino group and carbonyl O atom are involved in an intramolecular N—HO hydrogen bond. In the crystal, weak C—HO, C—HF and C—HCl interactions link the molecules into a three-dimensional network.
