本文用NMR的~1H谱和~(13)C谱确定了一系列万同取代基的熊果苷类似物和天麻苷类似物的结构,研究了熊果苷类似物的端基构型,指出了不同构型图谱的特征,用所得的结论推断出天麻苷类似物的端基构型为β型.
In this paper, the structures of arbutin analogs and gastrodin analogues of a series of syndiotactic substituents have been determined by the ~ 1H and ~ (13) C spectra of NMR. The terminal configuration of arbutin analogues has been studied. The characteristics of different configuration maps were deduced, and the conclusion was drawn that the terminal configuration of gastrodia analogues was β type.
