In the title compound, C13H14N2OS, four C atoms of the phenyl ring are disordered over two sets of sites in a 0.60 (3):0.40 (3) ratio. The heterocyclic ring is essentially planar (r.m.s. deviation = 0.017 Å) and forms dihedral angles of 82.0 (2) and 79.3 (3)°, respectively, with the major and minor occupancy components of the phenyl ring. The crystal packing features N—HO hydrogen bonds, which link the molecules into C(6) chains running parallel to the b axis.

In the title moleclue, C16H13ClN2O2, the cyclohexene ring is in a sofa conformation. The pyran ring is essentialy planar [maximum deviation = 0.038 (2) Å] and forms a dihedral angle of 89.68 (10)° with the benzene ring. In the crystal, molecules are linked by pairs of N—HN hydrogen bonds, forming inversion dimers with R22(12) ring motifs. These dimers are further linked by N—HO hydrogen bonds into chains along [110]. Weak C—HO hydrogen bonds are also present.

In the crystal structure of the title compound, C19H20N2O3·C3H6O, molecules are linked into inversion dimers with an R22(12) motif by pairs of N—HN hydrogen bonds. These dimers are further connected into chains running along the a axis by N—HO hydrogen bonds. C—HN and C—Hπ interactions also feature in the packing. The cyclohexene ring adopts nearly an envelope conformation [puckering parameters are QT = 0.456 (2) Å, θ = 54.6 (3)° and φ = 225.2 (3)°].
