Eleven triazole moiety-containing nucleotide analogs were synthesized starting form tetra-O-acetylribose in 55–63% total yields. The synthesis involved two key steps, the lipase-mediated selective deacylation of 1-azido-2,3,5-tri-O-acetyl-β-d-ribofuranoside and the Huisgen 1,3-dipolar cycloaddition between terminal alkynes and the 1-azido ribofuranoside derivative. These analogs showed inhibitory effects
从四-O-乙酰核糖开始合成了11个含三唑部分的核苷酸类似物,总产率为55-63%。合成涉及两个关键步骤,脂肪酶介导的1-叠氮基-2,3,5-三-O-乙酰基-β - d-核呋喃糖苷的选择性脱酰作用和末端炔烃与1之间的Huisgen 1,3-偶极环加成反应。 -叠氮核呋喃糖苷衍生物。这些类似物显示出对重组大肠杆菌NAD依赖性苹果酸酶的抑制作用。
