In the title compound, C15H17NO3, there are two molecules in the wherein the isoxazole rings make dihedral angles of 16.16 (15) and 16.79 (13)° with the benzene rings, and the cyclohexane rings adopt chair conformations. In both molecules, the hydroxyl groups of the diol fragments are cis oriented, the O—C—C—O torsion angles being 60.76 (12) and −55.86 (11)°. The two molecules are linked by a strong O—H⋯N hydrogen bond and the crystal packing is stabilized by one O—H⋯N and two O—H⋯O hydrogen bonds. An intramolecular O—H⋯O hydrogen bond is observed in one of the molecules.

5-Cyclohex-1-enyl-3-phenylisoxazole 1 was prepared according to the procedure described by Hansen et al. (2005), from benzaldehyde (2.00 ml, 20 mmol, Merck), hydroxylamine hydrochloride (1.46 g, 21 mmol), chloramine-T trihydrate (5.9 g, 21 mmol) and 1-ethynylcyclohexene (2.25 ml, 21 mmol, Aldrich), giving off-white solid (yield 93%).
1-(3-Phenyl-5-isoxazolyl)-1,2-cyclohexanediol (II), Scheme 2: To a mixture of dichloromethane (25 ml), water (25 ml) and tetrabutylammonium bromide (1.00 g) as phase transfer catalyst, were added 5-cyclohex-1-enyl-3-phenylisoxazole 1 (1.00 g, 4.4 mmol) and KMnO4 (2.78 g, 17.6 mmol). After dissolution, the reaction mixture was cooled at 273–283 K and vigorously stirred. Thereafter, the reaction mixture was sonicated for 30 min. The reaction was then quenched with sufficient ice cooled saturated Na2S2O5 (aq)to dissolve all of the manganese salts and the aqueous layer was saturated with NaCl then extracted repeatedly using dichloromethane. The organic layer was separated and dried (Na2SO4), concentrated in vacuo and the resulting product was purified by
(silica gel, petroleum ether, EtOAc) to afford pure title compound, giving off-white solid (yield 32%). Yellow block-shaped crystals of the title compound suitable for X-ray analysis were grown from a hexane/EtOAc solution (1:1 v/v) at 298 K over a period of a few days.C-bound H atoms were positioned geometrically with C—H = 0.93–0.98 Å and refined as riding model, with Uiso(H) = 1.2 Ueq(C) (for CH and CH2) or 1.5 times Ueq(C) (for CH3). O—H distances was constrained to 0.82 Å; Uiso(H) values were set at 1.2 Ueq(O) of the attached atom.

Experimental. Melting points were recorded on an Electrothermal 9100 instrument and are uncorrected; IR spectra were obtained on a Nicolet Nexus 470-FTIR spectrometer as potassium bromide pellets and are reported in wavenumbers (cm-1). 1H and 13CNMR spectra were measured on a Bruker AM-400 spectrometer (400 MHz), using CDCl3 as solvent. TMS was used as an internal standard. Chemical shifts (d) and J values are reported in p.p.m. and Hz, respectively. Reaction progress was monitored by means of thin-layer chromatography using Merck Kieselgel 60 (230–240 mesh). All reagents were purchased from Merck, Sigma and Aldrich Chemical Co. and used without further purification. Solvents were dried and distilled prior to use. 5-Cyclohex-1-enyl-3-phenylisoxazole 1: mp 361 (2) K.

Geometry. All s.u.'s (except the s.u. in the dihedral angle between two l.s. planes) are estimated using the full covariance matrix. The cell s.u.'s are taken into account individually in the estimation of s.u.'s in distances, angles and torsion angles; correlations between s.u.'s in cell parameters are only used when they are defined by crystal symmetry. An approximate (isotropic) treatment of cell s.u.'s is used for estimating s.u.'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 > 2σ(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. |

Potassium permanganate has been used vastly in functional group interconversion inorganic chemistry, (e.g., to oxidize alcohols to carbonyl compounds, for the cleavage or oxidation of carbon-carbon double bonds, oxidation of diols to lactones, and sulfides to sulfones (Singh & Lee, 2001). Permanganate has been used for the preparation of natural products as sylvaticin (Brown et al., 2008) and membrarollin (Morris et al., 2009) among others. In our search for bioactive nitrogen-containing compounds, we decided to oxidize 5-cyclohex-1-enyl-3-phenylisoxazole utilizing permanganate to obtain the title compound, since isoxazoles are a class of heterocyclic compounds having a remarkable number of applications and have been demonstrated to be very versatile building blocks in organic synthesis (Melo, 2005). We report here the crystal structure of the title compound.
In the crystal structure of the title compound, there two molecules in the asymmetric unit (Fig. 1). The isoxazole rings in the two molecules make dihedral angles of 16.16 (15) and 16.79 (12)° with the phenyl rings. In both molecules, the hydroxyl groups of the diol fragments are cis oriented, the O—C—C—O torsion angles being 60.76 (12) and -55.86 (11)°. The cyclohexane rings in both molecules adopt chair conformations as shown by the Cremer & Pople (1975) puckering parameters: Q = 0.570 (2) and 0.571 (3) Å, θ = 1.0 (2) and 0.0 (3)°, and ϕ = 292 (19) and 279 (9)°], respectively. Both of the molecules are linked by a strong O—H···N hydrogen bond and the crystal packing is stabilized by one O—H···N and two O—H···O type hydrogen bonds. Intramolecular O—H···O hydrogen bonds are observed in one of the molecules; details of hydrogen bonding geometry have been provided in Table 1. The crystal structure of a very closely related compound to (I) has been recently reported from our laboratory (Vallejos et al., 2009).
