(2E,4E)-1-(6-Chloro-2-methyl-4-phenyl-3-quinol­yl)-5-phenyl­penta-2,4-dien-1-one

Abstract

In the title compound, C27H20ClNO, the quinoline ring forms a dihedral angle of 62.53 (5)° with the substituent benzene ring. In the crystal, inter­molecular C—H(...)Cl inter­actions link the mol­ecules into chains along the b axis. Inter­molecular C—H(...)N and C—H(...)O hydrogen bonds further consolidate the structure into a three-dimensional network. The unit cell contains four solvent-accessible voids, each with a volume of 35 Å3, but no significant electron density was found in them.

Comment

The quinoline derivatives are very important compounds because of their wide occurrence in natural products and biologically active compounds (Markees et al., 1970; Campbell et al., 1998). A variety of natural compounds such as vinblastin, combretastatin A-4 and colchicine attack microtubules by interfering with the dynamics of tubulin polymerization and depolymerization, resulting in mitotic arrest. For a structurally simple group of compounds, chalcones have displayed an impressive array of biological activities, among which anti-malarial, anti-protozoal, anti-inflammatory, immunomodulatory, nitric oxide inhibition, tyronase inhibition, cytotoxic and anticancer activities have been cited in the literature (Bhat et al., 2005). In continuation our interest in synthesis of chalcones herein we report a new chalcone (Loh et al., 2010a,b; Shahani et al., 2010).

In the title compound (Fig. 1), the quinoline ring system (C1/N1/C2–C9) is approximately planar with a maximum deviation of 0.009 (1) Å at atom C1. This mean plane of quinoline ring system forms a dihedral angle of 62.53 (5)° with the benzene ring (C21–C26) attached to it. Another benzene ring (C15–C20) is linked with the quinoline ring system by a linkage of pentadione (C10–C14/O1) with a dihedral angle of 80.31 (5)° and the torsion angle between the linkage and the quinoline ring system, C8–C9–C10–C11 is 111.08 (13)°. Bond lengths and angles are comparable to closely related structures (Loh et al., 2010a,b; Shahani et al., 2010).

In the crystal packing (Fig. 2), intermolecular C11—H11A···Cl1 interactions (Table 1) link the molecules into chains down the b axis. Intermolecular C3—H3A···N1, C17—H17A···O1 and C27—H27C···O1 hydrogen bonds (Table 1) further consolidate the structure into a three-dimensional network. The unit cell contains four solvent-accessible voids each with a volume of 35 Å3. Application of the PLATON SQUEEZE procedure (Spek, 2009) showed no electron count in the void.

Experimental

A mixture of 3-acetyl-6-chloro-2-methyl-4-phenylquinoline (0.01 M) and cinnamaldehyde (0.01 M) and a catalytic amount of KOH in distilled ethanol was stirred for about 12 h, the resulting mixture was concentrated to remove ethanol then poured on to ice and neutralized with dilluted acetic acid. The resultant solid was filtered, dried and purified by column chromatography using 1:1 mixture of ethyl acetate and petroleum ether. M.P.: 416–417 K. Yield: 62 %. The solvent used for the crystallisation was a 1:1 mixture of ethyl acetate and petroleum ether.

Refinement

All H atoms were located from a difference Fourier map and refined freely [C–H = 0.965 (18) to 1.033 (19) Å].

Special details

Experimental. The crystal was placed in the cold stream of an Oxford Cryosystems Cobra open-flow nitrogen cryostat (Cosier & Glazer, 1986) operating at 100.0 (1) K.
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 > 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.
