Abstract top

In the title compound, C26H22N2O4, the central pyrrolidine ring adopts a twist conformation and the cyclopentane ring of the dihydroacenapthylene group adopts an envelope conformation with the spiro C atom as the flap. The naphthalene ring system of the dihydroacenaphthylene group forms dihedral angles of 83.4 (9) and 61.3 (7)°, respectively, with the mean planes of the pyrrolidine and indole rings. The crystal packing is stabilized by intermolecular C-H...O hydrogen bonds. The title compound is a diastereomer of a previously reported structure.

Comment top

We have recently reported the structure of a diastereomer of the title compound (Ganesh et al., 2013). Here we report the structural details of its diastereomer.

X–Ray analysis confirms the molecular structure and atom connectivity as illustrated in Fig. 1. The geometry of the acenaphthylene and pyrrolidine ring systems are comparable with the related structure (Wei et al., 2012). The sum of the angles at N1 [339.5 (1)°] and N2 [359.8 (1)°] of the pyrrolidine rings are in accordance with sp3 and sp2 hybridization. The naphthalene ring system [C7–C16] of the dihydroacenaphthylene group forms dihedral angles of 83.4 (9) and 61.3 (7)° with the central pyrrolidine ring [N1/C2–C5] and the indole ring [N2/C4/C17–C23]. The central pyrrolidine also makes a dihedral angle of 87.6 (9)° with the indole which shows that these two rings are almost perpendicular with each other.

The pyrrolidine rings [N1/C2-C5] adopts a twist conformation, on C4 and C5 atoms with puckering parameters of q2 = 0.470 (2) Å, φ = 128.1 (2) (Cremer & Pople, 1975). The cyclopentane ring [C5-C7/C12-C13] in the dihydroacenapthylene group adopts an envelope conformation [q2 = 0.074 (9)(2) Å and φ = 173.3 (2)°], and with atom C5 deviating by 0.044 (2) Å from the least-squares plane passing through the remaining four atoms (C13/C12/C7/C6) of that ring. In the crystal, the molecules are linked by intermolecular C20-H20···O3 and C1-H1B···O3 hydrogen bonds Fig. 2.

Experimental top

A mixture of 1 eq of (E)-methyl 2-(1-methyl-2-oxoindolin-3-ylidene) acetate, 1 eq of isatin and 1.5 eq of acenaphthylene-1,2-dione were dissolved in acetonitrile. This reaction mixture was refluxed at 353K for 8 hours. The reaction mixture was monitored for completion by thin layer chromatography. Upon completion, the the product was dried and purified by coloumn chromatography using ethyl acetate and hexane (1:9) as an elutent to affored pure dispiro oxindole. Yield (78%). Single crystals suitable for X-ray diffraction were obtained by slow evaporation of a solution of the title compound in ethyl acetate at room temperature.

Refinement top

All H atoms were fixed geometrically and allowed to ride on their parent C atoms, with C—H distances fixed in the range 0.93–0.98 Å with Uiso(H) = 1.5Ueq(C) for methyl H 1.2Ueq(C) for other H atoms.

Special details top

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.

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 > 2sigma(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.
