Cyclisation by double reductive amination of 2-acetamino-2-deoxy-D-xylo-hexos-5-ulose with N-2 protected L-lysine derivatives provided 2-acetamino-1,2-dideoxynojirimycin derivatives without any observable epimer formation at C-5. Modifications on the lysine moiety gave access to lipophilic derivatives that exhibited improved hexosaminidase inhibitory activities.
通过2-乙酰氨基-2-脱氧-D-木糖-己糖-5-酮与N-2保护的L-赖氨酸衍生物的双还原胺化反应进行环化,得到了2-乙酰氨基-1,2-二脱氧野尻霉素衍生物,且在C-5位没有观察到任何差向异构体的形成。对赖氨酸部分进行修饰可得到亲脂性衍生物,这些衍生物表现出改善的己糖胺酶抑制活性。
