摘要: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.
