the 1 C 4 conformation preponderates; the β anomer assumes mainly the 4 C 1 conformation. Thus, it is possible to deduce the structures of the N -phenyl- d -ribosylamines and to correlate some of the literature data. For 2,3- O -isopropylidene- d -ribofuranosylamine derivatives, the Δδ values for the 13 C-n.m.r. signals of the isopropylidene methyl groups can be used to establish the anomeric configuration
摘要Nmr光谱(1 H,13 C)已显示伯胺与d-核糖缩合,主要生成d-核糖吡喃糖基胺,其中1 C 4构象的α端基异构体占优势。β端基异构体主要呈现4 C 1构象。因此,有可能推论N-苯基-d-核糖胺的结构并使某些文献数据相关。对于2,3-O-异亚丙基-d-呋喃呋喃糖基胺衍生物,异亚丙基甲基的13 Cn.mr信号的Δδ值可用于建立异头构型。
