S1. 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 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.

S2. 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.

S3. Supra­molecular features

In the crystal, centrosymmetrically related molecules are linked into dimers forming rings of R₂²(10) graph-set motif. The dimers are further connected by C—H···O contacts forming rings of R₂²(8) graph-set motif, producing chains parallel to the b axis (Fig. 2).

S4. 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.

S5. Refinement

Crystal data, data collection and structure refinement details are summarized in Table 2. A l l 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.

Special details

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.
