Novel intermediates and method for the chemical synthesis of N-substituted 1,5-dideoxy-1,5-imino-L-fucitol derivatives are provided. A preferred intermediate is 1,5-dideoxy-1,5-imino-3, 4-O-isopropylidene-L-fucitol which is used to prepare the HIV inhibitor 1,5-dideoxy-1,5-imino-[N-.omega.-methyl caproate]-L-fucitol. These compounds are prepared in a short synthesis from the known compound 2,3-O-isopropylidene-D-lyxono-1,4-lactone or in a multi-step synthesis from D-galactose.
提供了一种新型中间体和方法,用于化学合成N-取代的1,5-二去氧-1,5-亚胺-L-富马醇衍生物。首选中间体是1,5-二去氧-1,5-亚胺-3,4-O-异丙基-L-富马醇,用于制备HIV抑制剂1,5-二去氧-1,5-亚胺-[N-.omega.-甲基己酸酯]-L-富马醇。这些化合物可以从已知化合物2,3-O-异丙基-D-利克松-1,4-内酯中短路径合成,或者从D-半乳糖中多步合成。
