2-O-isopropylidene-3,6-di-O-benzyl-5-deoxy-5-azido-α-D-glucofuranose. The latter afforded, after acidolysis followed by hydrogenolysis, 1-deoxynojirimicine and a small quantity of 1-deoxymannonojirimicine. The antibiotic thus obtained had an inhibitory effect on the trimming of N-linked carbohydrates in IgM.
容易获得的1,2 - O-异亚丙基-3 - O-苄基-α-D-葡萄糖呋喃糖经六步转化为1,2 - O-异亚丙基-3,6-二-O-苄基-5-脱氧- 5-叠氮基-α-D-葡萄糖呋喃糖。后者在酸解后进行氢解后,提供了1-deoxynonojirimicine和少量的1-deoxymannonojirimicine。如此获得的抗生素对IgM中N-连接的碳水化合物的修整具有抑制作用。
