The synthesis of novel tetrameric and hexameric mannoside clusters bearing 1,2,3-trizole linkages via Cu(I)-catalyzed azide-alkyne cycloaddition reaction ("click chemistry") is described. An attractive feature of these multiarmed mannoside clusters as potential inhibitors of uropathogenic Escherichia coli is the use of an aglycone whose length is designed to fit in the tyrosine gate. The acetylated
描述了通过Cu(I)催化的叠氮化物-炔烃环加成反应(“点击化学”)合成带有1,2,3-三唑键的新型四聚和六聚甘露糖苷簇。这些多臂甘露糖苷簇作为尿路致病性大肠杆菌的潜在抑制剂的一个吸引人的特征是使用了糖苷配基,其长度设计成适合酪氨酸门。乙酰化的甘露糖苷被去保护,并且发现相应的脱-O-乙酰化的甘露糖苷显示出良好的水溶性。
