Abstract top

The molecular conformation of the title compound, C41H29ClN4O3S, is stabilized by intramolecular C-H...O and C-H...Cl hydrogen bonds. The thiazole ring adopts an envelope conformation with the N atom as the flap, while the pyrrolidine ring has a twisted conformation on the N-C bond involving the spiro C atom. The [beta] lactam ring makes dihedral angles of 39.74 (15) and 16.21 (16)° with the mean planes of the thiazole and pyrrolidine rings, respectively. The thiazole ring mean plane makes dihedral angles of 23.79 (13) and 70.88 (13) ° with the pyrrolidine and cyclopentane rings, respectively, while the pyrrolidine ring makes a dihedral angle of 85.63 (13)° with the cyclopentane ring. The O atom attached to the [beta] lactam ring deviates from its mean plane by 0.040 (2) Å, while the O atom attached to the cyclopentane ring deviates from its mean plane by 0.132 (2) Å. In the crystal, molecules are linked by C-H...O hydrogen bonds, forming chains along [010], and C-H...[pi] and [pi]-[pi] interactions [centroid-centroid distance = 3.6928 (17) Å].

Comment top

The role of β-lactam antibiotics is well known (Banik & Becker, 2000). The most commonly used β-lactam antibiotics for the therapy of infectious diseases are penicillin and cephalosporin (Brakhage, 1998). In view of the potential applications of such compounds we have synthesized the title β-lactam derivative and report herein on its crystal structure.

In the title compound, Fig. 1, the thiazole ring (S1/N2/C18-C20) adopts an envelope conformation with atom N2 as the flap. The pyrrolidine ring (N2/C17/C18/C27/C28) adopts a twisted conformation on bond N2-C27. The β lactam ring (N1/C8/C9/C16) makes a dihedral angle of 39.74 (15)° with the thiazole ring mean plane, and a dihedral angle of 16.21 (16)° with the the pyrrolidine ring mean plane. The β lactam ring makes dihedral angles of 36.83 (16)° and 72.99 (16)° with the methoxy phenyl ring and unsubstituted phenyl ring, respectively. The thiazole ring mean plane makes a dihedral angle of 23.79 (13)° with the pyrrolidine ring mean plane, and a dihedral angle of 70.88 (13)° with the cyclopentane ring (C27/C31/C32/C37/C38) of the acenaphthylen-1(2H)-one ring system. The pyrrolidine ring mean plane is almost normal to the cyclopentane ring with a dihedral angle of 85.62 (13) °. Atom O2 deviates by 0.040 (2) Å from the β lactam ring and O3 deviates by 0.132 (2) Å from the cyclopentane ring. The chlorine atom Cl1 deviates by -0.0427 (8) Å from the phenyl ring to which it is attached.

In the crystal, molecules are linked by C—H···O hydrogen bonds, forming chains along the direction, and C-H···π and π-π interactions [Cg2-Cg3i = 3.6928 (17) Å; Cg2 and Cg3 are the centroids of rings C2-C6 and C32-C37, respectively; symmetry code: -x+1, y-1/2, -z]; see Table 1 and Fig. 2 for details.

Experimental top

A mixture of 2-(2-chlorophenyl)thiazolidine-4-carboxylic acid (1.1 mmol), acenapthenequinone (1.0 mmol) and 2-((1-(4-methoxycyclohexa-2,4-dienyl)-4- oxo-3-phenylazetidin-2-yl)methylene)malononitrile (1.0 mmol) was refluxed in methanol. Completion of the reaction was controlled by TLC. The solvent was removed in vacuo, then the crude product was diluted with chloroform and washed with water followed by brine solution. The organic layer was separated and dried over Na2SO4. The solvent was removed and the crude product was subjected to column chromatography using petroleum ether: ethyl acetate mixture (7:3) as eluent. The pure product was dried, dissolved in ethyl acetate and heated for two minutes. The resulting solution was subjected to crystallization by slow evaporation of the solvent for 48 hours giving colourless block-like crystals.

Refinement top

The atom coordinates correspond to the absolute structure of the molecule in the crystal [Falck parameter = 0.05 (5)]. The H atoms were placed in calculated positions and refined as riding: C—H = 0.93 - 0.97 Å with Uiso(H) = 1.5Ueq(C-methyl) and = 1.2Ueq(C) for other H atoms.

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.
