In the title compound, C27H25ClN2O3, the methylpyrrolidine ring adopts an with the N atom at the flap. The mean plane of the pyrrolidine ring makes dihedral angles of 82.1 (1), 84.4 (1) and 79.8 (1)°, respectively, with the adjacent benzene ring, the mean plane of the indoline ring system and the phenyl ring. The molecular structure is stabilized by intramolecular C—H⋯O hydrogen bonds. In the crystal, molecules are linked into chains along [101] by N—H⋯O hydrogen bonds. C—H⋯π interactions are observed between the chains.

A mixture of (E)-methyl 2-benzyl-3-(2-chlorophenyl)acrylate (2 mmol, 0.58 g), isatin (2 mmol, 0.29 g) and sarcosine (2 mmol, 0.18 g) in acetonitrile (8 ml) was refluxed for about 10 h. After the completion of the reaction as indicated by TLC, the reaction mixture was concentrated. Then the resulting crude mass was diluted with water (10 ml) and extracted with ethyl acetate (3×10 ml). The combined organic layers were washed with brine (2×10 ml) and dried overanhydrous Na2SO4. The organic layer was concentrated and the crude sample was purified by
on silica gel (Acme 100–200 mesh), using ethyl acetate:hexane (1:4) to afford the title compound as a colourless solid in 72% yield.Hydrogen atoms were positioned geometrically and allowed to ride on their parent atoms, with C—H = 0.93–0.97 Å and N—H = 0.86 Å, and with Uiso(H) = 1.5Ueq(C) for methyl H atoms and 1.2Ueq(C or N) for other H atoms.

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. |
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 > σ(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. |

Pyrrolidine-containing compounds are of significant importance because of their biological activities and widespread employment in catalysis (Witherup et al., 1995). Oxindole derivatives are of importance in the total synthesis of indole and oxindole alkaloids such as potent inhibitors of monoamine oxidase (MAO) in human urine and rat tissues (Glover et al., 1998). We report herein the crystal structure of the title compound.
In the molecule the pyrrolidine ring (N1/C8–C10) adopts an envelope conformation with N1 atom located at the flap position having asymmetry parameter (Nardelli, 1983) ΔCS (N1) = 5.21 (2) Å and with the puckering parameters (Cremer and Pople, 1975) q2 = 0.396 (2) Å and Φ2 = 172.6 (3)°. The sum of bond angles around N1 of the pyrrolidine ring [336.8 (1)°] is in accordance with sp3 hybridization. The bond length C17—O1 = 1.210 (1) Å indicates a keto group in the indoline. The pyrrolidine ring (N1/C8–C10) is almost equatorial with indoline (C10–C17/N2), chlorophenyl (C1–C6/Cl1) and phenyl (C19–C24) rings by making dihedral angles of 84.4 (1), 82.1 (1) and 79.8 (1)°, respectively. The indoline ring (C10–C17/N2) makes dihedral angles of 39.5 (2) and 61.2 (1)° with chlorophenyl(C1–C6/Cl1) and the phenyl (C19–C24) rings, respectively.
The structure is stabilized by an intermolecular N—H···O hydrogen bond and C—H···O intramolecular hydrogen bonds. The crystal structure is further consolidated by C—H ···Cg3 interactions, where Cg3 is the centroid of C11–C16 ring.
