(Received 21 September 2008; accepted 2 October 2008; online 9 October 2008)

The mol­ecule of the title compound, C23H23ClN2O4, contains a quinolyl unit linked to a functionalized pyrrolidine system with a 3,4-trans arrangement of the substituents. The unit cell contains two stereoisomers that have the absolute stereochemistry 3S,4R and 3R,4S. The pyrrolidine ring adopts a twist conformation with pseudo-rotation parameters P = 258.2 (3)° and τ(M) = 35.3 (1)°. The packing is stabilized by C—H⋯π inter­actions and offset π–π stacking (centroid-to-centroid distance = 3.849 Å, inter­planar distance = 3.293 Å and slippage = 1.994 Å) between phenyl rings, leading to a two-dimensional network.

Comment top

Quinolines derivatives have attracted considerable interest for many years due to their presence in the skeleton of a large number of bioactive compounds and natural products (Padwa et al., 1999; Sahu et al. 2002). For example, quinoline alkaloids, such as quinine, chloroquin, mefloquine and amodiaquine, are used as efficient drugs for the treatment of malaria (Robert & Meunier, 1998; Dow et al., 2006). On the other hand, pyrrolidine containing compounds are also of significant importance because of their biological activities and widespread employment in catalysis (Witherup et al., 1995; Kravchenko et al., 2005). As a part of our program related to the preparation and biological evaluation of quinolyl derivatives (Belfaitah et al., 2006; Bouraiou et al., 2008, 2007a,b; Rezig et al., 2000; Moussaoui et al., 2002), we have previously reported the preparation of some 3-pyrrolylquinoline derivatives via an 1,3-dipolar cycloaddition/oxydation key sequence from quinolinyl α,β-unsaturated esters as starting materials (Menasra et al., 2005). In a continuation of our efforts in this area, we report here the crystal structure of new N-phenylpyrrolidine derivative bearing a quinoline ring at C-3 and ester group at C-4 via an 1,3-dipolar cycloaddition reaction.

The asymmetric unit of title compound contains a quinolyl unit linked to a functionalized pyrrolidine system with a 3,4-trans arrangement of the substituents (Fig. 1). The two rings of quinolyl moiety are fused in an axial fashion and form a dihedral angle of 0.67 (6)° and this quasi plane system forms dihedral angles of 83.76 (7)° with the phenyl ring.The pyrrolidine was obtained with conservation of the stereochemistry of starting alkene, giving only one diastereoisomer with no evidence of any other isomers in the 1H NMR spectra or thin-layer chromatography of the crude product. X-ray crystallography of (I) showed an asymmetric unit which contains only one stereoisomer and the analysis of the unit cell demonstrate that the second stereoisomer is generated via a symmetry element. The two stereoisomers have for each one, the absolute stereochemistry 3S,4R and 3R,4S of the new stereocenters created in the cycloaddition reactions.

The pyrrolidine ring adopts twist conformation on C13—C14 with pseudorotation parameters P = 258.2 (3)° and τ(M) = 35.3 (1)° (Rao et al., 1981), the C13 atom deviates by 0.213 (2)Å from the mean plane through the remaining atoms.

The packing is stabilized by C—H···π interaction involving the C17—C22 phenyl ring (Table 1). Offset π···π stacking between this phenyl ring and the symmetry (-x, -y, -z) related ring might also be considered with a centroid-to-centroid distance of 3.849 Å, an interplanar distance of 3.293Å and a slippage of 1.994Å (Spek, 2003). These weak interactions build up a two dimensional network (Fig. 2).

Experimental top

The title compound I was synthesized by refluxing 1.0 mmol of (E)-methyl 3-(2-chloro-5,8-dimethoxyquinolin-3-yl) acrylate, 2.0 mmol of N-phenylglycine, and 5.0 mmol of CH2O in dry toluene (5.10-3 M). The contents were then cooled and filtered off and the filtrate was concentrated under reduced pressure. The residue was subjected to column chromatography (silica gel, eluent: CH2Cl2) to afford pure product. Crystals suitable for X-ray analysis were obtained by slow evaporation of a dichloromethane solution of (I).

Refinement top

All H atoms were localized on Fourier maps but introduced in calculated positions and treated as riding on their parent C atom.

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.
