The crystal and molecular structures of methyl α- l -fucopyranoside are reported. The sugar ring has the expected 1 C 4 conformation. The 1 H NMR spectrum at 600 MHz was fully analysed. The conformation of the pyranose ring in solution, derived from 3 J HH values, was very similar to that in the crystal. All these features have been rationalised through molecularmechanicscalculations.
摘要报道了甲基α-1-呋喃果糖苷的晶体和分子结构。糖环具有预期的1 C 4构象。全面分析了600 MHz处的1 H NMR光谱。从3 J HH值得出的溶液中吡喃糖环的构象与晶体中的构象非常相似。所有这些功能都通过分子力学计算得到了合理化。
