D-glucose derived pentodialdoses 11a-c on reduction followed by tosylation, azide displacement, hydrogenation and protection with -Cbz group gave N-Cbz protected compounds 14a-c, respectively, which on removal of 1,2-acetonide functionality and hydrogenation afforded corresponding 1-aza-sugars 3, 9 and 10 in good overall yields. The glycosidase inhibition activity of these 1-aza-sugars was tested with
D-葡萄糖衍生的戊二醛糖11a-c还原,然后进行甲苯磺酸化,叠氮化物置换,氢化和用-Cbz基团保护,分别得到N-Cbz保护的化合物14a-c,该化合物在除去1,2-丙酮化物官能团和氢化后提供相应的1-氮杂糖3、9和10的总产量良好。用甜杏仁作为不同糖苷酶的丰富来源测试了这些1-氮杂糖的糖苷酶抑制活性。
