In the title compound, C37H32N2O3, an intramolecular O—H⋯N hydrogen bond generates a five-membered ring, producing an S(5) motif. The piperidone ring adopts a half-chair conformation. The two fused pyrrolidine rings have similar envelope conformations. The interplanar angles between the benzene rings A/B and C/D are 75.68 (7) and 30.22 (6)°, respectively. In the adjacent molecules are interconnected into chains propagating along the [010] direction via intermolecular C—H⋯O hydrogen bonds. Further stabilization is provided by weak C—H⋯π interactions.

A mixture of 3,5-bis[(E)-(4-methylphenyl)methylidene]tetrahydro-4(1H)-pyridinone (0.100 g, 0.330 mmol), ninhydrin (0.059 g, 0.330 mmol) and phenylglycine (0.050 g, 0.330 mmol) were dissolved in methanol (10 ml) and refluxed for 1 h. After completion of the reaction as evident from TLC, the mixture was poured into water (50 ml). The solid precipitated was filtered and washed with water to afford the product which was recrystallized from ethyl acetate to reveal the title compound as colourless crystals.
Atoms H1N1 and H1O1 were located from difference Fourier map [N1—H1N1 = 0.853 (19) Å and O1—H1O1 = 0.98 (2) Å] and allowed to refine freely. The remaining H atoms were placed in their calculated positions, with C—H = 0.93 – 0.97 Å, and refined using a riding model, with Uiso = 1.2 or 1.5 Ueq(C). The rotating group model was applied to the methyl groups.
The versatility of 1,3-dipolar cycloadditions for the construction of five-membered heterocyclic rings is well established. The reaction of
with affords pyrrolidines which are present in numerous (Southon & Buckingham, 1989) and physiologically active compounds (Li et al., 1996). Spiropyrrolidines have received considerable attention due to its biological activity (Kozikowski, 1984; Howe & Shelton, 1990; De Amici et al., 1990; Ban et al., 1974). They display interesting anti-microbial, anti-tumor and antibiotic properties besides acting as inhibitors of human NK-I receptor activity (Okita & Isobe, 1994; Rosenmond et al., 1994; Kornet & Thio, 1976). The biological significance of the above mentioned heterocycles, prompted us to synthesize the title compound whose is presented here.The molecular structure of the title compound is shown in Fig. 1. An intramolecular O1—H1O1···N1 hydrogen bond (Table 1) forms a five-membered ring, generating an S(5) hydrogen bond ring motif (Bernstein et al., 1995). The 4-piperidone ring (N2/C15/C25-C28) adopts a half-chair conformation, with puckering parameters Q = 0.6128 (13) Å, θ = 36.28 (12)° and φ = 58.1 (2)° (Cremer & Pople, 1975). The two fused pyrrolidine rings with atom sequences C7/C8/C15/C16/N1 and C15/C16/C17/N2/C25, adopt similar envelope conformations, with atoms C8 and C25, respectively, as the flap atoms. The puckering parameters are Q = 0.3433 (14) Å, φ = 77.2 (2)° for the C7/C8/C15/C16/N1 pyrrolidine ring and Q = 0.4564 (13) Å, φ = 331.35 (17)° for the C15/C16/C17/N2/C25 pyrrolidine ring. The benzene rings A/B and C/D form interplanar angles of 75.68 (7) and 30.22 (6)°, respectively. The geometric parameters are consistent to those observed in closely related structures (Kumar et al., 2010a,b,c).
In the
adjacent molecules are interconnected into one-dimensional chains propagating along the [010] direction via intermolecular C22—H22A···O1 hydrogen bonds (Fig. 2, Table 1). Further stabilization is provided by weak intermolecular C3—H3A···Cg1 and C37—H37B···Cg2 interactions involving the C9-C14 (Cg1) and C18-C23 (Cg2) benzene rings.For general background to and applications of the title compound, see: Ban et al.

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1)K. |
Geometry. All esds (except the esd in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell esds are taken into account individually in the estimation of esds in distances, angles and torsion angles; correlations between esds in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell esds is used for estimating esds 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 > 2sigma(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 versatility of 1,3-dipolar cycloadditions for the construction of five-membered heterocyclic rings is well established. The reaction of azomethine ylides with alkenes affords pyrrolidines which are present in numerous alkaloids (Southon & Buckingham, 1989) and physiologically active compounds (Li et al., 1996). Spiropyrrolidines have received considerable attention due to its biological activity (Kozikowski, 1984; Howe & Shelton, 1990; De Amici et al., 1990; Ban et al., 1974). They display interesting anti-microbial, anti-tumor and antibiotic properties besides acting as inhibitors of human NK-I receptor activity (Okita & Isobe, 1994; Rosenmond et al., 1994; Kornet & Thio, 1976). The biological significance of the above mentioned heterocycles, prompted us to synthesize the title compound whose crystal structure is presented here.
The molecular structure of the title compound is shown in Fig. 1. An intramolecular O1—H1O1···N1 hydrogen bond (Table 1) forms a five-membered ring, generating an S(5) hydrogen bond ring motif (Bernstein et al., 1995). The 4-piperidone ring (N2/C15/C25-C28) adopts a half-chair conformation, with puckering parameters Q = 0.6128 (13) Å, θ = 36.28 (12)° and φ = 58.1 (2)° (Cremer & Pople, 1975). The two fused pyrrolidine rings with atom sequences C7/C8/C15/C16/N1 and C15/C16/C17/N2/C25, adopt similar envelope conformations, with atoms C8 and C25, respectively, as the flap atoms. The puckering parameters are Q = 0.3433 (14) Å, φ = 77.2 (2)° for the C7/C8/C15/C16/N1 pyrrolidine ring and Q = 0.4564 (13) Å, φ = 331.35 (17)° for the C15/C16/C17/N2/C25 pyrrolidine ring. The benzene rings A/B and C/D form interplanar angles of 75.68 (7) and 30.22 (6)°, respectively. The geometric parameters are consistent to those observed in closely related structures (Kumar et al., 2010a,b,c).
In the crystal structure, adjacent molecules are interconnected into one-dimensional chains propagating along the [010] direction via intermolecular C22—H22A···O1 hydrogen bonds (Fig. 2, Table 1). Further stabilization is provided by weak intermolecular C3—H3A···Cg1 and C37—H37B···Cg2 interactions involving the C9-C14 (Cg1) and C18-C23 (Cg2) benzene rings.
