Abstract top

In the title compound, C29H23ClN4O4, the quinazoline-indole system and the indolin-2-one system are each essentially planar, with maximum deviations from their mean planes of 0.150 (2) and 0.072 (2) Å, respectively. The central pyrrolidine ring adopts a twisted conformation on the C-C bond involving the spiro C atoms. Its mean plane forms dihedral angles of 83.37 (9) and 86.56 (8)°, respectively, with the indole rings of the indolin-2-one and quinazoline-indole systems. In the crystal, molecules are linked via pairs of N-H...O hydrogen bonds, forming inversion dimers. The dimers are linked via C-H...O hydrogen bonds, forming chains propagating along [001].

Comment top

Quinazolines are an important class of fused heterocycles with a wide range of biological activities such as anticancer (Wolfe et al., 1990), anti-inflammatory (Tereshima et al., 1995), and anti-HIV (Pandeya et al., 1999). In addition, quinazolines exhibit antibacterial and anti-fungal activities (Priya et al., 2011b).

In view of their importance and in continuation of our work on the crystal structure analysis of pyrrolidine and quinazoline derivatives, we report herein on the crystal structure of the title compound.

The molecular structure of the title molecule is illustrated in Fig. 1. The quinazoline-indole systems (N1/N2/C1-C15) and indolin-2-one system (N4/C22-C29), are essentially planar, with maximum deviations of 0.150 (2) Å for atom C1 and 0.072 (2) Å for atom C22 in the respective systems.

The central pyrrolidine ring (N3/C7/C16/C17/C22) is twisted on bond C7-C22 with puckering parameters of q2 = 0.4458 (2)Å, φ = 314.2 (2)° (Cremer & Pople, 1975). The mean plane of this ring forms dihedral angles of 83.37 (9) and 86.56 (8)° with the two indole rings (N4/C22-C29) and (N2/C1-C8), respectively. This clearly shows that the central pyrrolidine ring system and the two indole rings are almost perpendicular to one another.

In the crystal, molecules are linked via pairs of N-H···O hydrogen bonds forming inversion dimers. The dimers are linked via C-H···O hydrogen bonds forming chains propagating along the c axis direction. (Table 1).

Experimental top

Isatin (0.25 mmol) , sarcosine (0.3 mmol), (E)-ethyl 2-(8-chloro-12-oxoindolo[2,1-b]quinazolin-6(12H)-ylidene)acetate (0.25 mmol) in ethanol were refluxed for 120 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 eluted with n-hexane/EtOAc (8.5:1.5). The product was recrystallised from ethanol. Single crystals suitable for X-ray diffraction were obtained by slow evaporation of the solution of the title compound in ethanol at room temperature.

Refinement top

All the H atoms were fixed geometrically and allowed to ride on their parent C atoms: N-H = 0.86 Å, C—H = 0.93–0.97 Å with Uiso(H) = 1.5Ueq(C-methyl) and = 1.2Ueq(N,C) for other H atoms. The positions of the methyl hydrogens were optimized rotationally.

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.
