In the title compound, C₃₆H₃₁NO₄, two spiro links connect the methyl-substituted pyrrolidine ring to the acenaphthylene and cyclohexanone rings. The cyclohexanone ring is further connected to the dioxalane ring by a third spiro junction. The five-membered ring of the acenaphthylen-1-one ring system adopts a flattened envelope conformation with the ketonic C atom as flap, whereas the dioxalane and pyrrolidine rings each have a twist conformation. The cyclohexanone ring assumes a boat conformation. Three intramolecular C—H⋯O hydrogen bonds involving both ketonic O atoms as acceptors are present. In the crystal, C—H⋯O hydrogen bonds connect centrosymmetrically related molecule into chains parallel to the b axis, forming rings of R₂²(10)and R₂²(8) graph-set motifs.

Keywords: crystal structure; trispiropyrrolidines; acenaphthylene; spirocyclohexanones; dioxalane.

1. Chemical context

The biological properties of spiro compounds containing cyclic structures are evident from their presence in many natural products (Molvi et al., 2014 ). This class of compounds possesses pharmacological and therapeutic properties which play a fundamental role in biological processes. Several spiro compounds show diverse biological activities such as anticancer (Chin et al., 2008 ), antibacterial (van der Sar et al., 2006 ), anticonvulsant (Obniska & Kaminski, 2006 ), antimicrobial (Pawar et al., 2009 ), antituberculosis (Chande et al., 2005 ), anti-oxidant (Sarma et al., 2010 ) and pain-relief agents (Frank et al., 2008 ). Some spiro compounds are used as pesticides (Wei et al., 2009 ) and laser dyes (Kreuder et al., 1999 ). They are also used as electroluminescent devices (Lupo et al., 1998 ). The spiropyrrolidine-3,3′-indole ring system is a recurring structural motif in a number of natural products such as vinblastine and yincristrine which act as cytostatics in cancer chemotherapy (Tan et al., 1992 ). Spiro pyrrolidines act as inhibitors of human NK-I receptor activity (Kumar, Perumal, Manju et al., 2009 ). They are also exhibit antimicrobial (Sureshbabu et al., 2008 ), anticonvulsant and neurotoxic properties (Obniska et al., 2006 ) and antiproliferative activities (Almansour et al., 2014 ). Acenaphthalyene derivatives are found to have anti-inflammatory (Smith et al., 1979 ), antimicrobial (El-Ayaan & Abdel-Aziz, 2005 ), antifungal (McDavids & Daniels, 1951 ), antitumor (El-Ayaan et al., 2007 ) and insecticidal activities (Chen et al., 2014 ). Dioxalane moieties play a significant role in stabilizing the mutant HIV-1 RT and nucleoside triphosphate. They successfully act as nucleoside reverse transcriptase inhibitors (NRTIs) (Liang et al., 2006 ).

An efficient synthesis of dispiroindenoquinoxaline pyrrolizidine derivatives was accomplished by a one-pot four-component 1,3-dipolar cycloaddition reaction. A rare dispiroheterocyclic compound was synthesized through 1,3-dipolar cycloaddition of azomethine ylide for the purpose of designing a new class of complex dispiroheterocycles with potential biological activities. The reaction yielded a series of spiro [2, 2′] acenaphthen-1′-one-spiro[3,2′′]indane −1′,3′′-dione-4-aryl pyrrolizidines (Sureshbabu & Raghunathan, 2006 ). Novel spiro cyclohexanones have been synthesized by 1,3-dipolar cycloaddition of azomethine ylides with antituberculosis activity (Kumar, Perumal, Senthilkumar et al., 2009 ). Twelve novel acenaphthene derivatives were reported with antitumor activity (Xie et al., 2011 ). Geometric cis, trans isomers derivatives of 2-substituted-1,3-dioxolanes and 2-substituted-1,3-dioxanes have been designed and studied as antimuscarinic agents (Marucci et al., 2005 ). A series of new enantiomerically pure and racemic 1,3-dioxolanes was synthesized in good yields by the reaction of salicyaldehyde with commercially available diols using a catalytic amount of Mont K10 (Küçük et al., 2011 ).

The crystal structures of several biologically significant monospiropyrrolidines (Chandralekha et al., 2014 ) and dispiropyrrolidines (Palani et al., 2006 ) have been reported in the literature, but only few reports are available on the crystal structure of trispiropyrrolidines. In continuation of our work in this field, the crystal structure of title trispiropyrrolidine is reported on herein.

2. Structural commentary

In the title compound (Fig. 1), the methyl-substituted pyrrolidine ring (C12/C16/C17/N1/C19) is in a twist conformation with puckering parameters q2 = 0.3809 (18) Å, φ = −66.9 (3)°. The dioxalane ring (C10/O3/C14/C15/O4) also has a twist conformation [q2 = 0.327 (2) Å, φ = −58.7 (3)°], while the five-membered ring (C19/C20/C21/C26/C27) of the acenapnthylen-1-one ring system adopts a flattened envelope conformation [q2 = 0.0659 (18) Å, φ = −155.6 (16)°]. The six-membered cyclohexanone ring (C8–C13) adopts a boat conformation [Q_T = 0.616 (2) Å, θ = 75.36 (19)°, φ = 141.65 (18)°]. The least-squares mean plane through the pyrrolidine ring forms dihedral angles of 87.86 (6), 73.34 (7) and 87.81 (6)° with the mean planes of the attached benzene, cyclohexanone and cyclopentanone ring, respectively. The mean planes through the cyclohexanone and dioxalane rings form a dihedral angle of 77.99 (8)°. Bond lengths and angles are not unusual and in good agreement with the recently reported values of a related trispiropyrrolidine compound (Chandralekha et al., 2015 ). Three intramolecular C—H⋯O hydrogen bonds (Table 1) are present, involving both ketonic O atoms as acceptors.

3. Supramolecular features

In the crystal, centrosymmetrically-related molecules are linked into dimers forming rings of $[R_{2}^{2}]$ (10) graph-set motif. The dimers are further connected by C—H⋯O contacts forming rings of $[R_{2}^{2}]$ (8) graph-set motif, producing chains parallel to the b axis (Fig. 2).

4. Synthesis and crystallization

An equimolar mixture of 7,9-bis [(E)-benzylidine)]-1,4-dioxo-spiro[4,5]decane-8-ones (1 mmol) and sacrosine in methanol (25-30 ml) was refluxed for 4 h. After the completion of the reaction as indicated by TLC, the solid precipitate was filtered and washed with methanol to give the pure trispiropyrrolidine derivative. Single crystals suitable for the X-ray diffraction analysis were obtained by slow evaporation of the solvent at room temperature.

5. 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 Å and refined using a riding model approximation, with U_iso(H) = 1.2U_eq(C) or 1.5U_eq(C) for methyl H atoms. A rotating model was applied to the methyl groups.

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.
