In the title compound, C₃₈H₃₂N₄O₃·H₂O, the quinoxaline–indene and pyrrolizine systems are essentially planar, with maximum deviations from their mean planes of 0.162 and 0.563 Å, respectively. The pyrrolizine ring forms dihedral angles of 88.53 (5) and 89.95 (8)° with the quinoxaline–indene system and the indoline ring, respectively. The central pyrrolidine ring has an envelope conformation with the C atom bearing the quinoxaline-indene system as the flap. The pyrrolidine ring of the indole system adopts an envelope conformation with the C atom bonded to the pyrrolizine ring N atom as the flap. The five-membered ring attached to the central pyrolidine ring adopts a twisted conformation. In the crystal, O—H⋯N and O—H⋯O hydrogen bonds between water molecules and pyrrolizine N and carbonyl O atoms together with C—H⋯O interactions result in chains along [100].

Comment top

Spiro compounds have received considerable interest due to their highly biological properties (Pradhan et al., 2006); Thus more and more novel spiroheterocycle compounds have been prepared and characterized (Saeedi et al., 2010); Dandia et al., 2011). In addition , quinoxaline derivatives also showed various biological activites (He et al., 2003).

Pyrrolidine derivatives are found to have anticonvulsant, antimicrobial and antifungal activities against various pathogens (Amal Raj et al., 2003). Quinoxaline derivatives shown antibacterial, antiviral and anticancer properties (Zarranz et al., 2003). As spiro pyrrolidine compounds are of great medicinal properties, we have undertaken the three dimensional structure of the title compound. In view of these importance and continuation of our work on the crystal structure analyis of pyrrolidine and quinoxaline derivatives, the crystal structure of the title compound has been carried out and the results are presented here.

X-Ray analysis confirms the molecular structure and atom connectivity of the compound as illustrated in Fig. 1. The quinoxaline-indene systems (C1-C15/N1-N2) and pyrrolizine system (C15-C16/C34-C38/N4), are essentially planar, with maximum deviations from mean plane of -0.162 Å for C3 atom and -0.563 Å for C36 atom, respectively.

The pyrrolizine ring (C15-C16/C34-C38/N4) forms a dihedral angles of 88.53 (5) and 89.95 (6)° with quinoxaline-indene systems and indole ring (C16-C23/N3) respectively. This clearly shows that the quinoxaline-indene ring system and indole rings are almost perpendicular to the pyrrolizine ring. The central pyrrolidine ring (C15-C16/C34-C35/N4) is enveloped on C15 with the puckering parameters of q₂ = 0.4478 (2) Å, ϕ = 246.90 (2)° (Cremer & Pople, 1975). The pyrrolidine (C16-C18/C23/N3) of indole ring adopts envelope conformation on C16 with the puckering parameters of q₂ = 0.0729 (2) Å, ϕ = 243.08 (1)°. The five membered ring (C35-C38/N4) attached with the central pyrolidine ring adopts twisted conformation on C36-C37 with the puckering parameters of q₂ = 0.3767 (2) Å, ϕ = 92.96 (3)°.

In the crystal intra and intermolcular O-H···O hydrogen bonds between water molecules and pyrrolizine fragment N and carbonyl group O atoms of organic compound together with C-H···O interactions result in one-dimensional supramolecular structure.

Experimental top

Benzyl Isatin( 0.25 mmol), L-proline ( 0.3 mmol), Ethyl Indeno[1,2-b] quinoxalin-11-ylideneacetate( 0.25 mmol) (Azizian et al., 2005) in ethanol refluxed for 60 min. The progress of the reaction was followed by TLC. After completion, the solvent was removed under reduced pressure and the resulting crude product was subjected to column chromatography. The product was recrystallised from methanol. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of the solution of the title compound in methanol at room temperature.

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.
