The polyhydroxylated azepanes (3R,4R,5R,6R)-tetrahydroxyazepane (−)-1 and (3S,4S,5S,6S)-tetrahydroxyazepane (+)-1 are synthesised from D-and L-chiro-inositol, respectively. Key transformations in the reaction sequence include a glycol-fission reaction with sodium metaperiodate supported on silica gel and the double reductive amination of a manno-1,6-dialdehyde derivative. This work represents the first synthesis of tetrahydroxyazepanes from inositols.
多羟基氮杂环庚烷(3R,4R,5R,6R)-四羟基氮杂环庚烷(-)-1 和(3S,4S,5S,6S)-四羟基氮杂环庚烷(+)-1 分别由 D 和 L-螺肌醇合成。反应序列中的关键转化包括与硅胶支撑的偏碘酸钠发生的乙二醇裂变反应,以及甘露-1,6-二醛衍生物的双还原胺化反应。这项工作是首次从肌醇合成四羟基氮杂环庚烷。
