摘要: 本文报导了十个碳苷化合物的13C-NMR谱,其中四对是α、β端基异构体。研究结果发现,αβ异构体糖环各相应碳原子的13C-NMR的化学位移值有明显差异。β异构体糖环上各碳的化学位移值(除C4'外)均比α异构体相应碳大,而且各具特征数值。这一规律可用作区分碳苷的端基构型。此外尚讨论了糖的构型对苷元δc值的影响。

Abstract: 13C-NMR spectra of ten l-C-aryl-D-glucopyranoses, including four pairs of α,β anomers, were studied. Chemical shifts of the sugar moiety of β-anomers are larger than α-anomers (except C4'), which could be used to distinguish the α and β-anomers of 1-C-aryl D-glucopyranoses. In addition, the effects of configuration of sugar on the chemical shift data of the aglycone has beeu discussed.
