摘要
A mimic of a (1 -> 2),(1 -> 6)-mannotrioside was synthesized by replacing the central mannose unit with an enantiomerically pure. conformationally stable trans-diaxial cyclohexanediol. The three-dimensional structure of the molecule was investigated by NMR spectroscopy supported by molecular modelling and was compared to the known features of the natural mannotrioside.
