In the title compound, C21H23N3O4S·H2O, the methylsulfanyl group is disordered over two sets of sites with site-occupancy factors of 0.631 (11) and 0.369 (11). The dihydropyridine ring adopts an E4 conformation. In the crystal, classical O—H
N, O—HO and N—HO hydrogen bonds, as well as C—HO and C—HS contacts, connect the molecules into a three-dimensional network.

In the title compound, C19H16F3NO6, a quinoline derivative featuring an annealated furan substituent, the mean planes of the carboxy substituents are at an angle of 74.3 (2)°. In the crystal, C—HO contacts result in undulating chains along [110]. C—HF contacts also occur. The shortest centroid–centroid distance between rings is 3.3376 (7) Å, involving two furan rings of neighbouring molecules.

In the title compound, C8H8Br2O2, all non-H atoms lie essentially in a common plane (r.m.s deviation of all fitted non-H atoms = 0.0330 Å). In the crystal, weak C—HO hydrogen bonds connect the molecules, forming chains which extend along the b-axis direction.
O hydrogen bonds connect the molecules, forming chains which extend along the b-axis direction.
