The title compound, C14H18O5S, is an important intermediate for the synthesis of poly(amidoamine) dendrimers. The cyclohexane ring adopts a chair conformation with its two substituents in equatorial positions. In the molecules form centrosymmetric dimers via O—H⋯O hydrogen bonds.

trans-4-(methoxycarbonyl)cyclohexanemethanol (10 mmol), triethylamine (10 mmol) and a small amount of trimethylamine hydrochloride were suspended in dichloromethane (20 mL), benzenesulfonyl chloride (11 mmol) was dropped with vigorous stirring at room temperature, after 1 h the reaction was quenched by addition of water. The organic layer separated was evaporated to give an oil and the oil was hydrolyzed in methanol and aqueous NaOH (11 mmol) solution for 5 h at 323 K. Then the title compound was obtained by acidification with hydrochloride and recrystallized from acetone. Colorless crystals suitable for X-ray analysis were obtained by slow evaporation in cyclohexane and acetone at room temperature.
H atoms were positioned geometrically (C—H = 0.93–0.98 Å, O—H = 0.82 Å) and refined using a riding model, with Uiso(H) = 1.2Ueq(C,O).

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. |

PAMAM (poly(amidoamine)) dendrimers have attracted much interest for their symmetry, high degree of branching and high density of terminal functional groups, which can participate in different reactions. The modification of periphery of PAMAM dendrimer which aimed to change the physical or chemical properties of PAMAM dendrimers, have been reported recently (Grabchev et al.,2003; Ahmed et al.,2001; Wang et al.,2004). To improve the lipophilicity of PAMAM dendrimers and provide a new type of linker with special stereostructure, a series of cyclohexane derivatives were synthesized.
The crystal structure shows that molecules are mainly linked by O—H···.O hydrogen bonds and the cyclohexane ring of the title compound exists in the chair conformation.
