fucofuranoside method, a recently devised technique for determining the absoluteconfiguration of secondaryalcohols by 13C NMR, the arabinofuranoside method is proposed. Unlike fucose, the derivatizing agent arabinofuranose tetraacetate is available quantitatively by acid treatment of arabinose followed by acetylation. Application to the ten alcohols, previously tested for fucofuranoside method, showed essentially
作为呋喃呋喃糖苷方法的简单替代品,提出了一种最近设计的通过13 C NMR测定仲醇的绝对构型的技术,即阿拉伯呋喃糖苷方法。与岩藻糖不同,阿拉伯糖呋喃糖四乙酸酯可通过酸处理阿拉伯糖然后进行乙酰化来定量获得。到10醇,先前针对fucofuranoside方法测试的应用程序,显示基本上相同的Δ δ Ç和Δ δ ħ值,表明D-阿拉伯呋喃糖苷方法是用于确定仲醇的绝对构型同样有用。
