In the title compound, C21H21BrClNO4, the dihydropyridine ring adopts a flattened boat conformation. The 3-bromo-5-chloro-2-hydroxyphenyl ring forms a dihedral angles of 84.44 (7)° with the dihydropyridine mean plane. The molecular conformation is stabilized by an intramolecular O—HO hydrogen bond, with an S(8) ring motif. In the crystal, O—HO and C—HO hydrogen bonds link the molecules, forming a three-dimensional network.

In the title compound, C19H17NO2, the dihedral angle between the benzene ring and the naphthalene ring system is 9.72 (5)°, while the torsion angle of the C—N—C—C bridging group is 179.24 (17)°. The methyl group of the 1-phenylethanol moiety is disordered over two positions with a refined occupancy ratio of 0.775 (5):0.225 (5). The molecular conformation is stabilized by an intramolecular N—HO hydrogen bond, which generates an S(6) ring motif. In the crystal, molecules are linked by O—HO hydrogen bonds, forming zigzag chains propagating along the c-axis direction. Neighbouring chains are linked via C—HO interactions, forming a two-dimensional slab-like network parallel to the bc plane.

In the title molecule, C14H15NO3, the ring system is essentially planar, with an r.m.s. deviation of 0.003 Å. The atoms of the ethane-1,2-diol group were refined as disordered over two sets of sites in a ratio of 0.815 (3):0.185 (3). The molecular conformation is stabilized in part by an intramolecular N—HO hydrogen bond, which forms an S(6) ring. In the crystal, molecules are connected by N—HO and O—HO hydrogen bonds, forming a two-dimensional network parallel to (100). The network also features weak C—HO hydrogen bonds. Weak C—Hπ interactions also observed.
