In the title compound, C21H23NO3S, both the thiazole and oxazolidine rings adopt twist conformations. The mean plane of the thiazole ring makes a dihedral angle of 61.02 (7)° with the oxazolidine ring mean plane, and dihedral angles of 22.72 (6) and 75.07 (6)° with the benzene rings. The benzene rings are almost perpendicular to one another, making a dihedral angle of 89.14 (6)°. There are bifurcated intramolecular C—H
O hydrogen bonds in the molecular structure. In the crystal, molecules are linked via C—Hπ interactions, forming chains propagating along [100].

In the title molecular salt, C6H9N2+·C7H4NO4−, the original pyridine N atom of 2-amino-4-methylpyridine is protonated and the carboxylic acid group of nitrobenzoic acid is deprotonated. In the crystal, the ions are linked by N—HO hydrogen bonds, forming chains propagating along [001]. The chains are linked via C—HO hydrogen bonds, forming two-dimensional networks lying parallel to the bc plane.

In the title compound, C16H16Cl2N4, the imidazole ring mean plane makes a dihedral angle of 70.01 (1)° with the phenyl ring. The Cl atoms deviate by −0.0472 (6) and 0.0245 (8) Å from the plane of their attached benzene ring. In the crystal, molecules are linked via pairs of C—HN hydrogen bonds, forming inversion dimers.

In the title compound, C28H25N3O4, the central pyrrolidine ring adopts adopts an envelope conformation with the N atom as the flap and the piperidine ring adopts a chair conformation. The pendant pyrrolidine ring is almost planar (r.m.s. deviation = 0.008 Å). An intramolecular C—HO interaction closes an S(6) ring. In the crystal, inversion dimers linked by pairs of N—HO hydrogen bonds generate R22(8) loops.
