Abstract

In the title compound, C38H28F2N2O2, the piperidine ring adopts a chair conformation and the pyrrolidine ring adopts an envelope conformation with the spiro C atom as the flap atom. The naphthalene ring system makes dihedral angles of 39.89 (8), 35.33 (8) and 46.45 (8)° with the two fluoro-substituted benzene rings and the phenyl ring, respectively, while the dihedral angle between the two fluoro-substituted benzene rings is 75.21 (10)°. An intra­molecular O—H⋯N hydrogen bond generates an S(5) ring. In the crystal, mol­ecules are connected by C—H⋯O hydrogen bonds, forming supra­molecular chains propagating along the c-axis direction. Weak C—H⋯π inter­actions further consolidate the structure.
