cis-N-(2-Hydroxycyclohexyl)-p-toluenesulfonamide

M. I. Fadlalla, H. B. Friedrich, G. E. M. Maguire and M. D. Bala

There are two symmetry-independent molecules in the asymmetric unit of the title compound, C₁₃H₁₉NO₃S. The cyclohexane rings in the two molecules adopt chair configurations. The hydroxy and amino groups on the cyclohexane ring assume axial and equatorial orientations, respectively, with respect to the plane of the ring. The crystal structure is stabilized by two intermolecular N—H

O and O—H

O hydrogen bonds from the two symmetry-independent molecules.

Comment top

Molecules containing a β-amino alcohol system have been used as precursors for the synthesis of chiral ligands, aziridine and biologically active compounds (Bergmeier, 2000; Krzemiński & Wojtczak, 2005). As a part of study on this family of compounds, we report the crystal structure of the title compound (l) (Fig. 1).

The geometry of the benzenesulfonamide unit in (I) agrees with that for related structures (Chinnakali et al. 2007; Nan & Xing, 2006). The cyclohexane rings in the two molecules adopt the chair configuration. The hydroxy and amino groups on the cyclohexane ring respectively assume axial and equatorial orientations with respect to the plane of the ring. The crystal packing (Fig. 2) is stabilized by intermolecular N—H···O and O—H···O hydrogen bonds from the two neighbouring symmetry-independent molecules (Table 1).

Experimental top

The synthesis of the title compound was carried out using a modified literature method (Naiker et al. 2008) using a catalytic process. To a nitrogen saturated Schlenk tube, toluene (6 ml), water (172 µl) chloroamine-T (0.21 g, 0.956 mmol), cyclohexene (0.478 mmol) and catalyst (0.03 g) were added in that order. After the complete conversion of the starting material the catalyst was gravity filtered. The reaction mixture was washed with 15 ml of sodium sulfite (1 g in 15 ml of de-ionized water), followed by 15 ml of ethyl acetate. Then the aqueous layer was separated from the organic layer and washed further with 3 × 15 ml of ethyl acetate. The solvent was removed in vacuo, and the crude product was purified using preparative high pressure liquid chromatography to yield the title compound as a white solid. Single crystals suitable for X-ray diffraction were prepared by evaporation of a solution of the title compound in acetonitrile/water (1:1 v/v) at room temperature.

Special details top

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.
