Crystal structure of methyl 3′-benzamido-4′-(4-meth­oxy­phen­yl)-1′-methyl­spiro­[indeno­[1,2-b]quinoxaline-11,2′-pyrrolidine]-3′-carboxyl­ate

In the title compound, the mean plane through pyrrolidine ring is approximately orthogonal to the mean plane of the cyclo­pentane ring, making a dihedral angle of 88.78 (10)°. An intra­molecular N—H⋯N inter­action is observed. The crystal packing features C—H⋯O hydrogen bonds.

Abstract

In the title compound, C₃₅H₃₀N₄O₃, the spiro C atom connects the five-membered pyrrolidine ring and the indeno­quinoxaline ring system. The pyrrolidine ring adopts a twist conformation. An intra­molecular N—H⋯N inter­action between the amino group and the pyrazine ring is observed. In the crystal, mol­ecules are linked by a pairs of C—H⋯O hydrogen bonds, forming inversion dimers.

Chemical context  

Spiro pyrrolidine derivatives act as potential anti­leukemic (Abou-Gharbia & Doukas, 1979 ▸), anti­convulsant (Jiang et al., 2006 ▸), anti­viral (Lundahl et al., 1972 ▸) and anti-inflammatory (Hussein & Abdel-Monem, 2011 ▸) agents. Indeno­quinoxaline derivatives possess anti­metabolism properties (Sehlstedt et al., 1998 ▸) and find applications in dyes. They are also used as building blocks for the synthesis of organic semiconductors (Gazit et al., 1996 ▸).

The synthesis of di­spiro­indeno­quinoxaline pyrrolidine derivatives has been achieved by one-pot four-component 1,3-dipolar cyclo­addition reaction (Suresh Babu & Raghunathan, 2008 ▸) while ninhydrin-based one-pot four-component condensation reaction yielded novel alkyl­spiro­[indeno­[1,2-b]quinoxaline-11,3′-pyrrolizine]-2′-carboxyl­ate derivatives (Karsalary et al., 2010 ▸). A series of original spiro­pyrrolizidine derivatives was synthesized by a one-pot three-component [3 + 2] cyclo­addition reaction; these exhibit extensive hydrogen bonding in the crystalline state (Haddad et al., 2015 ▸).

Structural commentary  

In the title compound (Fig. 1 ▸), the four-fused-ring system of the 11H-indeno­[1,2-b]quinoxaline unit is approximately planar and forms a dihedral angle of 59.16 (7)° with the C29–C34 methyl­benzene ring. The methyl-substituted C7/C16/C26/C27/N4 pyrrolidine ring is in a twist conformation with puckering parameters Q(2) = 0.4238 (18) Å and φ = 215.8 (2)°. The mean plane through the C7/C16/C26/C27/N4 pyrrolidine ring is approximately orthogonal to the mean plane of the C5–C9 cyclo­pentane ring, subtending a dihedral angle of 88.78 (10)°. The mean plane of the pyrrolidine ring makes a dihedral angle of 70.33 (10)° with the attached benzene ring. The sum of bond angles around nitro­gen atom of the pyrrol­idine ring (337.11°) is in agreement with sp ³ hybridization. An intra­molecular N—H⋯N hydrogen bond stabilizes the mol­ecular conformation (see Table 1 ▸ and Fig. 2 ▸).

Supra­molecular features  

In the crystal, symmetry-related enanti­omeric mol­ecules are linked through pairs of C—H⋯O inter­actions (Table 1 ▸), forming dimers with an (10) graph-set motif. This inter­molecular C—H⋯O hydrogen bond, along with the intra­molecular N—H⋯N inter­action, plays an important role in stabilizing the packing of the mol­ecules.

Database Survey  

A search of the Cambridge Structural Database (Version 5.36, last update May 2015; Groom et al., 2016 ▸) revealed that the number of compounds containing a pyrrolidine ring is 2420 and a quinoxaline unit is 1265. Out of these entries, only 14 compounds were found to possess both pyrrolidine and quinoxaline ring systems. The geometry of the pyrrolidine ring of the title compound compares well with those reported for similar structures, for example, 4-ferrocenyl-1-methyl-3-benzoyl­spiro­[pyrrolidine-2,11′-indeno­[1,2-b]-quinoxaline (refcode: EDUSED; Vijayakumar et al., 2012 ▸). The bond lengths and bond angles of quinoxalin unit are in good agreement with reported values of a related structure (refcode: MOKNUX; Chandralekha et al., 2014 ▸). The N—H⋯N hydrogen bond is a rare occurrence in these type of compounds (refcodes: IFOQIF, NINVEN, NIPDUN, LOSKAH, HOWCIH, BENDEF, CEFDOI, EDUSED).

Synthesis and crystallization  

A mixture of ninhydrin (1 mmol) and 1,2-phenyl­enedi­amine (1 mmol) were stirred for 15 min in methanol (10 mL). Then, to this was added a solution of 4-(4-methyl­benzyl­idene)-2-phenyl-4H-oxazole-5-one (1 mmol) and sarcosine (1 mmol) in methanol (10 mL). The reaction mixture was refluxed for 16–18 h and the progress of the reaction was monitored by TLC. After the completion of the reaction as evidenced by TLC, the excess solvent was removed under vacuum and the crude product was purified by column chromatography using a mixture of petroleum ether and ethyl acetate as eluent (4:1). Single crystals suitable for the X-ray diffraction analysis were obtained by slow evaporation of the solvent at room temperature.

Refinement  

Crystal data, data collection and structure refinement details are summarized in Table 2 ▸. All H atoms were placed in calculated positions, with C—H = 0.93–0.98 and N—H = 0.86 Å, and were refined using a riding-model approximation, with U _iso(H) = 1.2U _eq(C, N) or 1.5U _eq(C) for methyl H atoms. A rotating model was applied to the methyl groups.

Special details

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.
