In the title compound, C22H16N2O3, the naphthalene ring, the 1,4-dihydropyridine ring and the cyclopent-2-enone ring are nearly coplanar, with the dihedral angles between the neighbouring rings being 1.93 (11) and 2.30 (9)°, respectively. The benzene ring group at position 7 and the 1,4-dihydropyridine ring form a dihedral angle of 78.75 (4)°. Intermolecular N—H⋯O hydrogen bonds and C—H⋯π interactions stabilize the crystal packing.

The title compound was synthesized according to the procedure (Heravi et al. 2010). A round-bottomed flask was charged with 3-nitrobenzaldehyde (1 mmol), cyclopentane-1,3-dione (1 mmol), 1-naphtylamine (1 mmol), acetic acid (5 ml), and H6P2W18O62.18H2O (0.01 mmol). The reaction mixture was stirred until completion (monitored by TLC). Then the mixture was poured into ice water. The precipitated products were separated by filtration, washed with water, recrystallized in a dimethylformamide-ethanol (DMF-EtOH) solution. The recrystallization gave single-crystals suitable for X-ray diffraction.
The hydrogen atom bonded to the nitrogen atom was positioned from a Fourier difference map refined freely. All other H atoms were placed in calculated positions, with C—H = 0.95 Å, 0.99Å or 1.00Å and included in the final cycles of
using a riding model, with Uiso(H) = 1.2Ueq(parent atom).Data collection: CrystalClearSM Expert (Rigaku/MSC, 2009); cell

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. |

The 1,4-dihydropyridine (1,4-DHP) derivatives exhibits various bioactivities, including sedative-hypnotic activity (Zheng et al. 2011), inhibition of the α 4-integrin-paxillin interaction (Ginsberg et al. 2011), anti-microbial activities (Nadaraj et al. 2009),and antitumor activity (Husson et al. 2011). These reports inspired us to study the relationship between their structures and activities. During the synthesis of 1,4-dihydropyridine (1,4-DHP) derivatives, the title compound, (I) was isolated and its structure was determined by X-ray diffraction. Herein we report its crystal structure.
In the molecular structure (Fig. 1), the naphthalene ring, the 1,4-dihydropyridine ring and the cyclopent-2-enone ring adopt planar conformations with RMS of 0.0201 Å, 0.0235 Å and 0.0058 Å, respectively. The largest deviation of these rings are 0.033 (1) Å(C2), 0.038 (1) Å(C3), 0.008 (1) Å(C5), respectively. The fused ring system is almost coplanar, for the dihedral angle between the neighboring rings are 1.93 (0.11) ° and 2.30 (9)° respectively. The planar 3-nitrophenyl ring at position 7 and the 1,4-dihydropyridine ring forms a dihedral angle of 78.75 (4)°. The crystal packing is stablized by the intermolecular N—H···O hydrogen bond and C—H···π interactions (Fig. 2, Table 1).
