The first synthesis of 1,2-trans-homoiminosugars devised as mimics of β-d-GlcNAc and α-d-ManNAc is described. Key steps include a regioselective azidolysis of a cyclic sulfite and a β-amino alcohol skeletal rearrangement applied to a polyhydroxylated azepane. The β-d-GlcNAc derivative has been coupled to serine to deliver an iminosugar C-amino acid. The two homoiminosugars demonstrate moderate glycosidase
1,2-所述第一合成反式-homoiminosugars设计为模仿β- d -GlcNAc和α- d -ManNAc进行说明。关键步骤包括环状亚硫酸盐的区域选择性叠氮化和应用于多羟基化沸腾石的β-氨基醇骨架重排。β- d- GlcNAc衍生物已与丝氨酸偶联以递送亚氨基糖C-氨基酸。两种高同亚氨基糖显示出适度的糖苷酶抑制作用。
