In the title compound, C31H30N4O, the central pyrrolidine ring adopts an with the methylene C atom being the flap. The quinoxaline and indane rings are each planar, having r.m.s. deviations of 0.030 and 0.050 Å, respectively. The pyrrolidine ring mean plane forms dihedral angles of 88.25 (1) and 83.76 (1)° with the quinoxaline and indane rings, respectively. Intramolecular C—H⋯O and C—H⋯N interactions are observed. In the crystal, C—H⋯π interactions lead to helical supramolecular chains along the b-axis direction.

A mixture of 1-methyl-3-[E-(4-methylphenyl)methylidene]tetrahydro-2(1H)- pyridinone (1 mmol), ninhydrin (1 mmol), o-phenylenediamine (1 mmol) and sarcosine (1 mmol) in methanol was refluxed for 3–4 h. After completion of the reaction as indicated by TLC the reaction mixture was poured into cold water. The solid precipitate obtained was filtered and dried. The product was purified by
using petroleum ether:ethylacetate mixture (90:10 v/v). Suitable crystals were obtained by recrystallizing the product from methanol. Yield: 37%, M. pt: 498–500 K.H atoms were placed at calculated positions and allowed to ride on their carrier atoms with C—H = 0.93–0.98 Å, and with Uiso = 1.2Ueq(C) for CH2 and CH groups, and Uiso = 1.5Ueq(C) for CH3 groups. The (-1 1 1) reflection was affected by the beam-stop and was removed from the final refinement.

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 F.2 are statistically about twice as large as those based on F, and R-factors based on ALL data will be even larger. |

Pyrrolidine-containing compounds are of significant importance because of their biological activities and widespread employment in catalysis (Witherup et al., 1995). Heterocycles with piperidine sub-structures display important biological activities, such as cytotoxic (El-Subbagh et al., 2000) and anti-cancer (Dimmock et al., 2001) besides being useful as synthons in the construction of alkaloid natural products (Lee et al., 2001). The high medicinal value of these compounds, in conjunction with our research interests, prompted us to synthesize and report the X-ray studies of the title compound.
In the title compound (Fig. 1), the central pyrrolidine ring is an envelope on C2 with asymmetry parameters ΔCs(C2) = 7.1 (2)° and puckering parameters q2 = 0.4303 (18) Å and ϕ2 = 211.5 (2)° (Cremer & Pople, 1975). The quinoxaline and the indane group forms dihedral angles of 88.25 (1) and 83.76 (1)°, respectively, with the central pyrrolidine ring. The quinoxaline ring system (C12—C17/N3,N4) is planar, with r.m.s. deviation = 0.030 Å. The indane group is also planar with r.m.s deviation = 0.050 Å. The dihedral angle between the mean planes of the fused quinoxaline and the indane groups is 8.43 (1)°, indicate that the fused rings is slightly folded about the C12—C13 bond. The six-membered ring, N2/C41—C45, exhibits a twisted chair conformation, as indicated by the asymmetry parameters ΔCs(N2) = 7.58 (16)°, ΔCs(C45) = 7.58 (16)° and with the puckering parameters Q = 0.558 (2) Å, Θ = 164.1 (2)° and Φ = 207.1 (8)°. The torsion angle C4—C42—N2—C42 is -167.62 (16)° and corresponds to an antiperiplanar conformation. The sum of bond angles around N1(339.9°) and N2 (331.4°) indicate the atoms N1 and N2 are each in a pyramidal geometry. Weak intramolecular C—H···O, N interactions are observed (Table 1). In the crystal structure, C—H···π interactions, involving the benzene ring C14···C19, lead to the helical supramolecular chains along the b axis, as shown in Fig. 2.
