cis-4-(Methoxycarboxyl)cyclohexanemethanol (10 mmol), pyridine (11 mmol) and a small amount of 4-dimethylaminopyridine were dissolved in dichloromethane (20 ml), then p-toluenesulfonyl chloride (11 mmol) was added dropwise with vigorous stirring at room temperature. After 8 h the reaction was quenched by addition of water and the organic layer separated was evaporated under vacuum, the solid obtained was hydrolyzed in a mixed solution of methanol and aqueous NaOH (11 mmol) for 4 h at 323 K. The title compound was then obtained by acidification with hydrochloric acid followed by recrystallization from ethyl acetate. Colorless crystals suitable for X-ray analysis were obtained by slow evaporation in ethyl acetate at room temperature.
The H atoms were placed in the calculated positions in the riding model approximation with C—H = 0.93 (aromatic-H) and 0.96 (methyl-H), O—H = 0.82 Å (hydroxyl) and with Uiso(H) = 1.2Ueq(aromatic-C) and 1.5Ueq(methyl-C, hydroxyl). Methyl and hydroxyl H atoms were allowed to rotate around the C—C and C—O axis but not to tilt to best fit the experimental electron density.

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. |

Some aminocarboxylic acid derivatives are used as anti-ulcer agents (Hoshina et al., 1984). To find new anti-ulcer agents, a series of trans/cis-cyclohexanecarboxylic acid derivatives were designed and synthesized.
In this paper, we want to report the synthesis and structure of the title compound, cis-4-(tosyloxymethyl)cyclohexanecarboxylic acid.
The cyclohexane ring exhibits a chair conformation and the cyclohexane C—C bond lengths and C—C—C endocyclic angles are in the range found for similar compounds (van Koningsveld, 1972) (Fig.1). They agree well with those of trans-4-(tosyloxymethyl)cyclohexanecarboxylic acid (Qi et al., 2008).
In the crystal structure, two molecules form centrosymmetric dimers via O—H···O hydrogen bonds (Fig. 2).
