4-Methyl-2-[(E)-phen-yl(1,2,3,4-tetra-hydro-1-naphthyl-imino)meth-yl]phenol.

In the crystal structure of the title compound, C(24)H(23)NO, the phenyl ring makes dihedral angles of 81.53 (11) and 75.35 (12)°, respectively, with the methyl-substituted and the fused benzene rings. The dihedral angle between the two benzene rings is 71.10 (10)°. There is an intra-molecular O-H⋯N hydrogen bond.

4-Chloro-2-((1R)-1-{[(R)-(2-chloro-phen-yl)(cyclo-pent-yl)meth-yl]amino}eth-yl)phenol.

The title compound, C(20)H(23)Cl(2)NO, was prepared by condensation of (R)-1-(2-chloro-phen-yl)-1-cyclo-pentyl-methanamine with 1-(5-chloro-2-hydroxy-phen-yl)ethanone, resulting in the formation of a new chiral center. The structural analysis confirms the absolute configuration of the title compound and the formation of the (R,R) diastereoisomer. There is an intra-molecular O-H⋯N hydrogen bond which stabilizes the conformation of the mol-ecule. The mol-ecules are linked to each other through weak C-H⋯π inter-actions.

4-Chloro-2-((1R)-1-{[(R)-(2-chlorophen-yl)(cyclo-pent-yl)meth-yl]amino}prop-yl)phenol.

In the title compound, C(21)H(25)Cl(2)NO, the dihedral angle between the two benzene rings is 33.18 (11)°. The five-membered ring adopts an envelope conformation. There is an intra-molecular O-H⋯N hydrogen bond. In the crystal, mol-ecules are linked by weak N-H⋯Cl hydrogen bonds, forming a helical chain along the c axis.
