Abstract 3-Acetamido-2,3,5,6-tetradeoxy-5-fluoro- d , l -ribo-hexofuranose was synthesized by direct, fluorinative dehydroxylation of methyl 3-acetamido-2,3,6-trideoxy- d , l -arabino-hexopyranoside with sulfur tetrafluoride-hydrogen fluoride. The furanose form and the ribo configuration, indicated by 13C- and 1H-n.m.r. spectroscopy, respectively, were confirmed by a single-crystal, X-ray diffraction
摘要通过对3-乙酰氨基-2,3,6-三苯甲基-d,l进行直接的氟代脱羟基反应,合成了3-乙酰氨基-2,3,5,6-四脱氧-5-氟-d,1-核糖-六呋喃糖。 -阿拉伯糖基己吡喃糖苷与四氟化硫-氟化氢。呋喃糖形式和核糖构型分别由13C-和1H-nmr光谱表示,已通过单晶X射线衍射研究确定。
