A series of enantiomerically pure azasugars (2,5-dideoxy-2, 5-imino-D-mannitol, 1-deoxynojirimycin, 1-deoxymannojirimycin, and related compounds) was synthesized from D-mannitol via aminoheterocyclization of C2-symmetric bis-epoxides and subsequently followed by ring isomerization in few cases. These compounds have been evaluated as inhibitors of several glycosidases (alpha- and beta-D-glucosidases
通过C2-对称双环氧化物的氨基杂环化反应,由D-甘露醇合成了一系列对映体纯的氮杂糖(2,5-dideoxy-2、5-imino-D-甘露醇,1-deoxynojirimycin,1-deoxymannojirimycin和相关化合物)。在少数情况下随后进行环异构化。这些化合物已被评估为几种糖苷酶(α-和β-D-葡糖苷酶,α-D-甘露糖苷酶和α-L-岩藻糖苷酶)的抑制剂。抑制研究显着地表明,多羟基化的氮杂环庚烷是糖苷酶的抑制剂,Ki在微摩尔范围内。
