In the title compound, C41H31N3O3, the pyrazole and pyrrolidine rings adopt twisted conformations. The mean plane of the pyrazole ring forms dihedral angles of 9.11 (12) and 39.65 (11)° with the phenyl rings. The O atoms deviate from the mean planes of the chromene and acenaphthylene ring systems by 0.194 (15) and 0.079 (15) Å, respectively. In the crystal, molecules are linked via pairs of C—H⋯O interactions,forming inversion dimers with an R22(12) ring motif.

A mixture of acenaphthenequinone (1.05 mmol), L–proline (1.1 mmol) and dipolarophile (1.0 mmol) in ethanol was refluxed for 5 hrs and cooled to room temperature. The solid formed in the reaction mixture was poured into a beaker containing crushed ice and it was filtered, dried, and recrystallized from ethanol to obtain the pure product in good yield (89%) without involving column chromatography.
Hydrogen atoms were placed in calculated positions with C—H = 0.93Å to 0.98Å and refined in the riding model with fixed isotropic displacement parameters: Uiso(H) = 1.5Ueq(C) for methyl group and Uiso(H) = 1.2Ueq(C) for other groups.
Pyrazole derivatives in general are well known nitrogen containing
and have been the subject of enormous research due to their importance in various applications and their widespread potential biological and pharmacological activities such as antimicrobial (Mahajan et al., 1991), antiviral (Baraldi et al., 1998), antitumor (Katayama & Oshiyama, 1997) and antifungal activities (Chen & Li, 1998).The molecular structure of the title compound C41H31N3O3, is shown in Fig. 1. The mean planes of the phenyl rings (C1–C6) and (C10–C15) form a dihedral angle of 31.31 (12)° between them. The mean plane of the pyrazole ring (C7/C8/C9/N1/N2) forms dihedral angles of 9.11 (12)° and 39.65 (11)° with the mean planes of the two phenyl rings (C1–C6) and (C10–C15), respectively. The mean plane of the pyrrolizine ring (C16–C22/N3) forms dihedral angles of 63.95 (9)° and 74.46 (8)° with the mean planes of the chromene ring (C17/C23–C30/O1) and the acenaphthylene ring (C18/C31–C41), respectively. The oxygen atoms O2 and O3 deviate from the least square planes of the chromene ring (C17/C23–C30/O1) and acenaphthylene ring (C18/C31–C41) by -0.194 (15)Å and -0.079 (15)Å, respectively. The title compound exhibits structural similarities with an already reported related structure (Jagadeesan et al., 2013).
The sum of angles around the N3 atom (335.6°) indicates sp3 φ2 = 170.9 (3)°. Also, the atoms C22 and N3 deviate from the mean planes of the remaining ring atoms by 0.182 (2)Å and -0.201 (16)Å, respectively. The other pyrrolidine ring (C19–C22/N3) also adopts a twisted conformation on C19 and N3 with puckering parameters of q2 = 0.382 (2)Å and φ2 = 205.1 (4)°. Also, the atoms C19 and N3 deviate from the mean planes of the remaining ring atoms by 0.237 (2)Å and -0.219 (18)Å, respectively.
The pyrrolidine ring (C16/C17/C18/C22/N3) adopts a twisted conformation on C22 and N3, with puckering parameters (Cremer & Pople, 1975) of q2 = 0.322 (18)Å andThe crystal packing is stabilized by C22—H22···O3i intermolecular hydrogen bond interaction, which generates R22(12) graphset ring motif (Bernstein, et al., 1995). The symmetry codes: (i) -x, y-1, z-1 (Table 1). The packing view of the title compound is shown in Fig. 2.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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. |

Pyrazole derivatives in general are well known nitrogen containing heterocyclic compounds and have been the subject of enormous research due to their importance in various applications and their widespread potential biological and pharmacological activities such as antimicrobial (Mahajan et al., 1991), antiviral (Baraldi et al., 1998), antitumor (Katayama & Oshiyama, 1997) and antifungal activities (Chen & Li, 1998).
The molecular structure of the title compound C41H31N3O3, is shown in Fig. 1. The mean planes of the phenyl rings (C1–C6) and (C10–C15) form a dihedral angle of 31.31 (12)° between them. The mean plane of the pyrazole ring (C7/C8/C9/N1/N2) forms dihedral angles of 9.11 (12)° and 39.65 (11)° with the mean planes of the two phenyl rings (C1–C6) and (C10–C15), respectively. The mean plane of the pyrrolizine ring (C16–C22/N3) forms dihedral angles of 63.95 (9)° and 74.46 (8)° with the mean planes of the chromene ring (C17/C23–C30/O1) and the acenaphthylene ring (C18/C31–C41), respectively. The oxygen atoms O2 and O3 deviate from the least square planes of the chromene ring (C17/C23–C30/O1) and acenaphthylene ring (C18/C31–C41) by -0.194 (15)Å and -0.079 (15)Å, respectively. The title compound exhibits structural similarities with an already reported related structure (Jagadeesan et al., 2013).
The sum of angles around the N3 atom (335.6°) indicates sp3 hybridization. The pyrrolidine ring (C16/C17/C18/C22/N3) adopts a twisted conformation on C22 and N3, with puckering parameters (Cremer & Pople, 1975) of q2 = 0.322 (18)Å and φ2 = 170.9 (3)°. Also, the atoms C22 and N3 deviate from the mean planes of the remaining ring atoms by 0.182 (2)Å and -0.201 (16)Å, respectively. The other pyrrolidine ring (C19–C22/N3) also adopts a twisted conformation on C19 and N3 with puckering parameters of q2 = 0.382 (2)Å and φ2 = 205.1 (4)°. Also, the atoms C19 and N3 deviate from the mean planes of the remaining ring atoms by 0.237 (2)Å and -0.219 (18)Å, respectively.
The crystal packing is stabilized by C22—H22···O3i intermolecular hydrogen bond interaction, which generates R22(12) graphset ring motif (Bernstein, et al., 1995). The symmetry codes: (i) -x, y-1, z-1 (Table 1). The packing view of the title compound is shown in Fig. 2.
