The title compound, C22H20N2O, was obtained from the condensation reaction of 3-formylbenzonitrile, 2-naphthol and pyrrolidine. There are two molecules in the having similar conformations. Intramolecular O—H⋯N and C—H⋯O hydrogen bonds occur, with only between molecules. The dihedral angles between the naphthalene ring system and the phenyl ring in the two molecules are 75.28 (10) and 76.07 (11)°. The five-membered rings adopt half-chair conformations.

3-Formylbenzonitrile (1.97 g, 0.015 mol) and pyrrolidine (1.065 g, 0.015 mol) was added to 2-naphthol (2.16 g, 0.015 mol) without solvent under nitrogen. The temperature was raised gradually to 120°C in one hour and the mixture was stirred at this temperature for 12 h. The system was treated with 30 ml of ethanol 95% and cooled. The precipitate was filtered and washed with a small amount of ethanol 95%. The title compound was isolated using
(petroleum ether:ethyl acetate 4:1 v/v). Single crystals suitable for X-ray were obtained by slow evaporation of an ethyl acetate solution at room temperature.All H atoms were positioned geometrically and refined using a riding model, with C—H = 0.93–0.97 Å, O—H = 0.82 Å, and with Uiso(H) = 1.2 Ueq(C) or 1.5 Ueq(O). In the absence of significant
effects, the 3377 Friedel pairs were merged. The relatively high Rint value and the low data/parameter ratio reflects the poor quality of the crystal.Over one hundred years ago, Betti developed a straightforward synthesis involving the condensation of 2-naphthol, ammonia and equivalents of benzaldehyde, followed by the addition of HCl and KOH to yield 1-(a-aminobenzyl)-2-naphthol. This product which possesses an asymmetric carbon center is known as a Betti base. Betti-type reaction is an important method to synthesize chiral ligands and by this method many unnatural homochiral amino-phenol compounds have been obtained (Lu et al. 2002; Xu et al. 2004; Wang et al. 2005). Here we report the synthesis and
of the title compound, 3-[(2-hydroxynaphthalen-1-yl)(pyrrolidin-1-yl)methyl]benzonitrile (Fig. 1).Both molecules in the
have the same relative conformation at the chiral carbon atoms. The naphthalene (A; C1–C10, B; C23–C32) and benzene (C; C16–C21, D; C34–C39) rings are strictly planar and the dihedral angles between A/C and B/D are 75.28 (10) and 76.07 (11)°, respectively. The two molecules are stabilized by intramolecular O—H···N hydrogen bonding, whereas only one is involved in intramolecular C—H···O hydrogen bonds (Table 1). Intermolecular interactions are only van der Waals forces.For the applications of Betti-type reactions, see: Lu et al. (2002); Xu et al. (2004); Wang et al. (2005)

Geometry. All e.s.d.'s (except the e.s.d. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell e.s.d.'s are taken into account individually in the estimation of e.s.d.'s in distances, angles and torsion angles; correlations between e.s.d.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell e.s.d.'s is used for estimating e.s.d.'s involving l.s. planes. |
Refinement. Refinement of F2 against ALL reflections. The weighted R-factor wR and goodness of fit S are based on F2, conventional R-factors R are based on F, with F set to zero for negative F2. The threshold expression of F2 > σ(F2) is used only for calculating R-factors(gt) etc. and is not relevant to the choice of reflections for refinement. R-factors based on F2 are statistically about twice as large as those based on F, and R- factors based on ALL data will be even larger. |

Over one hundred years ago, Betti developed a straightforward synthesis involving the condensation of 2-naphthol, ammonia and equivalents of benzaldehyde, followed by the addition of HCl and KOH to yield 1-(a-aminobenzyl)-2-naphthol. This product which possesses an asymmetric carbon center is known as a Betti base. Betti-type reaction is an important method to synthesize chiral ligands and by this method many unnatural homochiral amino-phenol compounds have been obtained (Lu et al. 2002; Xu et al. 2004; Wang et al. 2005). Here we report the synthesis and crystal structure of the title compound, 3-[(2-hydroxynaphthalen-1-yl)(pyrrolidin-1-yl)methyl]benzonitrile (Fig. 1).
Both molecules in the asymmetric unit have the same relative conformation at the chiral carbon atoms. The naphthalene (A; C1–C10, B; C23–C32) and benzene (C; C16–C21, D; C34–C39) rings are strictly planar and the dihedral angles between A/C and B/D are 75.28 (10) and 76.07 (11)°, respectively. The two molecules are stabilized by intramolecular O—H···N hydrogen bonding, whereas only one is involved in intramolecular C—H···O hydrogen bonds (Table 1). Intermolecular interactions are only van der Waals forces.
