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-ω-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.
本研究提供了用于化学合成 N-取代型 1,5-二脱氧-1,5-亚氨基-L-岩藻糖醇衍生物的新型中间体和方法。一种优选的中间体是 1,5-二脱氧-1,5-亚氨基-3, 4-O-异亚丙基-L-岩藻糖醇,它可用于制备 HIV 抑制剂 1,5-二脱氧-1,5-亚氨基-(N-ω-甲基己酸酯)-L-岩藻糖醇。这些化合物是由已知化合物 2,3-O-异亚丙基-D-来苏诺-1,4-内酯通过简短合成法或由 D-半乳糖通过多步合成法制备的。
