In the title compound, C28H27ClN2O3S, the central imidazolidine ring adopts an with the C atom bearing the chlorophenyl ring at the flap. The geometry around the S atom is distorted tetrahedral. Three methylene groups of the cyclohexene ring are disordered over two sets of sites [site occupancies = 0.562 (10) and 0.438 (10)]. The crystal packing is stabilized by C—H⋯π interactions.

4-Toluenesulfonyl azide (1.3 mmol), 1-ethynyl cyclohexene (1.2 mmol), 4-chlorophenyl N-phenylnitrone (1.0 mmol) and triethylamine (2 mmol) were successively added to Cu1—Y zeolite (30 mg) in dichloromethane under N2 atmosphere. After stirring at room temperature for the 6 h, the mixture was diluted with dichloromethane. After removing the catalyst by filtration, followed by solvent evaporation, the resulting crude product was finally purified by
(silica gel). Single crystals suitable for X-ray diffraction were obtained by slow evaporation of a solution of the title compound in acetone at room temperature.Three methylene groups of the cyclohexane ring are disordered over two positions (C25/C25', C26/C26' and C27/C27') with refined occupancies of 0.562 (10) and 0.438 (10). The corresponding bond distances involving the disordered atoms were restrained to be equal. All H atoms were fixed geometrically and allowed to ride on their parent C atoms, with C—H distances fixed in the range 0.93–0.97 Å with Uiso(H) = 1.5Ueq(C) for methyl H 1.2Ueq(C) 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. |

Sulfonamides have widely been recognized for their wide variety of pharmacological activities such as antibacterial, antitumor, anti-carbonic anhydrase, diuretic, hypoglycaemic, antithyroid and protease inhibitory activity. Sulfonamides have also been used clinically as antimalarial agents (Zareef et al., 2007), particularly sulfadiazine and sulfadoxine. Due to their significant pharmacology applications and widespread use in medicine, these compounds have also gained attention in bioinorganic and metal-based (Chohan et al., 2008) drug chemistry. Sulfonamide derivatives are well known drugs and are used to control diseases caused by bacterial infections. Benzene sulfonamide derivatives are known to exhibit anticancer and HIV activities (Pomarnacka & Kozlarska-Kedra, 2003) and antibacterial activities (Nieto et al., 2005). Imidazolidine compounds are important intermediates and building blocks in the construction of various biologically active compounds (Wang et al., 1995). Against this background, and in order to obtain detailed information on molecular conformations in the solid state, an X-ray study of the title compound was carried out.
X-Ray analysis confirms the molecular structure and atom connectivity as illustrated in Fig. 1. The geometry around the S atom is distorted tetrahedral, comprising two O atoms of the sulfonyl group, a C atom of a phenyl ring and the imidazolidine N atom. The S–O, S–C, and S–N distances are 1.416 (2), 1.747 (2) and 1.677 (2) Å, respectively, these are comparable as observed in similar structures (Ranjith et al., 2011). The atom Cl1 is deviated by 0.136 (1)Å from the leastsquares plane of the rings C9–C14. The S atom exhibits significant deviation from that of a regular tetrahedron, with the largest deviations for the O–S–O [O1–S1–O2 121.2 (9)°] and O–S–N angles [O1–S1–N1 106.4 (7)°]. The widening of the angles may be due to repulsive interactions between the two short S=O bonds, similar to what is observed in related structures (Ranjith et al., 2011).
The imidazolidine ring adopts envelope conformation, with the puckering parameters q2 and ϕ (Cremer & Pople, 1975) and the smallest displacement asymmetric parameters,Δ, (Nardelli et al., 1983) as follows: q2=0.1230 (17) Å, ϕ=211.7 (8)°, Δs(C8)=1.50 (17) and the cyclohexane ring adopts half-chair conformation, in addition to with the puckering parameters q2 and ϕ (Cremer & Pople, 1975) and the smallest displacement asymmetric parameters,Δ, (Nardelli et al., 1983) as follows: q2=0.399 (7) Å, ϕ=127.2 (8)°, Δs(C24)= 18.4 (7). In the crystal, the molecules form layers that are linked by π···π stacking interactions between the imidazolidine and benzene [C9—C14] rings [centroid–centroid distances = 3.7406 (9) Å].
