protecting-group-free asymmetric synthesis of 1,2,4-trideoxy-1,4-imino-L-xylitol is readily achieved in five steps from 2-deoxy-D-ribose and with an overall yield of 48%. Key in this synthesis is the application of our recently developed Vasella-reductive amination and carbamate annulation methodologies to the synthesis of 2-deoxy-aza-sugars. The carbamate annulation occurred with excellent yield and
1,2,4-三脱氧-1,4-亚氨基-L-木糖醇的无保护基不对称合成可通过5步从2-脱氧-D-核糖轻松实现,总产率为48%。该合成的关键是我们最近开发的 Vasella 还原胺化和氨基甲酸酯环化方法在 2-脱氧氮杂糖的合成中的应用。氨基甲酸酯环化以优异的产率和非对映选择性 (>20:1 dr) 发生,有利于 3,4-顺式异构体。
