In the title molecule, C18H15NO2, the atoms in the carbazole unit deviate from planarity [maximum deviation from mean plane = 0.1317 (12) Å]. The pyrrole ring makes dihedral angles of 1.01 (8) and 18.56 (10)° with the benzene and furan rings, respectively. The cyclohexene ring adopts a half-chair conformation. In the crystal, pairs of N—H
O hydrogen bonds form an R22(10) ring. Molecules are further linked by C—HO and C—Hπ interactions, forming a three-dimensional network.

The asymmetric unit of the title compound, C21H27NO, contains two molecules (A and B). In molecule A, the central ring of the anthrone unit adopts a shallow boat conformation and the dihedral angle between the benzene rings is 18.96 (7)°. In molecule B, the central ring is close to being planar (r.m.s. deviation = 0.078 Å) and the dihedral angle between the aromatic rings is 7.82 (7)°. In the crystal, molecules are linked by O—HN hydrogen bonds, forming zigzag C(7) chains of alternating A and B molecules running parallel to [100]. The structure also features weak C—HO and C—Hπ interactions.

In the crystal structure of the title compound, C14H11BrClNO4S, the molecules form inversion dimers with R22(8) motifs through pairs of N—HO hydrogen bonds. The benzene rings are not coplanar and subtend a dihedral angle of 66.27 (8)°. The carbomethoxy group makes a dihedral angle of 75.1 (1)° with the ring to which it is attached.
