Azasugars were obtained in one-pot reactions by catalytic reduction reactions of amino group precursors in aldosugars followed by intramolecular reductive amino alkylation reactions. (3R,4S)-4-[(1S)-1,2-Dihydroxyethyl]pyrrolidin-3-ol was obtained from D-xylose by two different strategies through 3-C-cyano-3-deoxy-D-ribo-pentofuranose or 3-C-azidomethyl-3-deoxy-D-ribo-pentofuranose in 6 and 16% overall
一锅反应中的氮杂糖是通过醛糖中氨基前体的催化还原反应,然后进行分子内还原性氨基烷基化反应而获得的。(3R,4S)-4-[(1S)-1,2-二羟乙基]吡咯烷-3-醇是通过两种不同的策略通过3-C-氰基-3-脱氧-D-核糖-戊呋喃糖从D-木糖获得的或3-C-叠氮基甲基3-脱氧-D-核糖-戊呋喃糖,总收率分别为6%和16%。在相应的Fmoc-氮杂糖中二醇基团的氧化裂解,然后脱保护,得到(3R,4R)-4-(羟甲基)吡咯烷丁-3-醇。(3R,4S)-4-[(1S,2R)-1,2,3-三羟丙基]吡咯烷-3-醇是由双丙酮-D-葡萄糖通过3-脱氧-3-C-硝基甲基-D-阿洛糖合成的总产率为7%。
