Catalytic hydrogenation then afforded the corresponding vicinal amino alcohols. Oximation of 1,4:3,6-dianhydrofructose with hydroxylamine, followed by hydrogenation, gave 2-amino-1,4:3,6-dianhydro-2-deoxymannitol. All compounds were elucidated by their HRMS, 1H NMR, 13C NMR, and IR spectra. The absolute configurations of the amino sugar derivatives were confirmed by single-crystal X-ray analysis or
通过硝基烷基与1,4:3,6-双脱水果糖的亨利反应合成2-C-硝基烷基-1,4:3,6-双脱水甘露醇。然后催化氢化得到相应的邻位氨基醇。用羟胺氧化1,4:3,6-二脱水果糖,然后氢化,得到2-氨基-1,4:3,6-二脱水-2-脱氧甘露糖醇。通过HRMS,1H NMR,13C NMR和IR光谱阐明了所有化合物。通过单晶X射线分析或NOESY光谱研究证实了氨基糖衍生物的绝对构型。提出了硝基2-C-硝基烷基糖加氢的可能机理。提出了硝基和氨基糖衍生物的稠合呋喃环的构象。
