In the title compound, C(19)H(19)NO, the dihedral angle between the naphthyl ring system and the phenyl ring is 79.83 (6)°. An intra-molecular O-H⋯N hydrogen bond, together with van der Waals inter-actions, stabilizes the mol-ecular conformation.

In the title compound, C(21)H(23)NO, obtained via a one-pot synthesis, an intra-molecular O-H⋯N hydrogen bond stabilizes the mol-ecular conformation. The dihedral angle between the fused ring system and the phenyl ring is 78.27 (5)°. The crystal packing is characterized by helical chains of mol-ecules linked by C-H⋯O hydrogen bonds.

In the title compound, C(23)H(25)NO, an intra-molecular O-H⋯N hydrogen bond defines the mol-ecular conformation; the naphthol mean plane and the benzene ring form a dihedral angle of 75.8 (2)°. The piperidine ring adopts a chair conformation. The crystal packing exhibits no short inter-molecular contacts.

In the title compound, C(17)H(11)ClN(2)O(3), an intra-molecular O-H⋯N hydrogen bond influences the mol-ecular conformation; the naphthol system and the substituted benzene ring form a dihedral angle of 3.5 (1)°. In the crystal, weak inter-molecular C-H⋯O hydrogen bonds link mol-ecules into chains in the [010] direction The crystal packing exhibits π-π inter-actions between the aromatic rings fr...

The complex structure of aminobenzylnaphthols can be easily obtained with the useful Betti reaction. These valuable compounds give rise to chiral intermediates, that found wide application in asymmetric synthesis. 1-[(1S)-(4-Fluorophenyl)-((1′S)-1′-naphthalen-1-yl-ethylamino)-methyl]-naphthalen-2-ol 1 was treated triflic anhydride yield corresponding (S,S)-triflate 2, which is a intermediate fu...
