-arabinofuranosides of various aliphatic alcohols were synthesized and then investigated by n.m.r. spectroscopy. The 13 C-n.m.r. glycosylation shift of these l -arabinofuranosides is very similar to that of l -arabinopyranosides and other glycopyranosides reported previously. The 3 J H-1,H-2 value of these α- l -arabinofuranosides is significantly different from that of the β anomers and can be used
摘要合成了各种脂肪醇的1-阿拉伯呋喃糖苷的端基异构对,然后通过核磁共振波谱研究。这些1-阿拉伯呋喃糖苷的13 Cn.mr糖基化转变与先前报道的1-阿拉伯吡喃果糖苷和其他糖吡喃糖苷的转变非常相似。这些α-1-阿拉伯呋喃糖苷的3 J H-1,H-2值与β端基异构体的3 J H-1,H-2值显着不同,可用于确定端基构型。然而,与糖吡喃糖苷的情况相反,1-阿拉伯呋喃糖苷的每个异头异构系列的1 J C-1,H-1值彼此非常相似。还通过核磁共振波谱研究了一些含有1-阿拉伯呋喃糖苷单元的二糖。
