    • (c) Conformationally unconstrained polyols, in general, prefers intermolecular to intramolecular O-H⋯O hydrogen bonding. The latter not only entails a high energy conformation with axial OH groups, but also a loss of one O-H⋯O hydrogen bond per intramolecular H-bond formed. For a recent article, see: A. Bonnet, J. Chisholm, W. D. S. Motherwell and W. Jones, CrystEngComm, 2005, 7, 71-95.

    • (a) The hydroxyl groups in 1 and 2 are locked in an 'axial-rich' conformation owing to the transfusion of the hydrocarbon ring with the cyclohexanetetrol moiety. For a detailed account of the strategy involved, see: G. Mehta, S. S. Ramesh and M. K. Bera, Chem. Eur. J., 2003, 9, 2264-2272.

    • The synthetic procedure adopted for the preparation of the tetrol 1 is a tactical modification of an earlier report, see: P. J. Garatt and F. Sondheimer, J. Chem. Soc. C, 1967, 565. The authors reported a tetrol of undetermined stereochemistry, melting in the range 253-256 uC. The present study therefore not only provides an unambiguous formulation of 1, but also enables one to identify the previously reported tetrol as corresponding to the major a-polymorph of 1.
