Three new phosphoramidites exhibiting two or three alkyne functions were prepared and introduced at the 5′ end of oligonucleotides. The resulting bis- and tris-alkyne oligonucleotides were conjugated with acetylthiohexyl, ferrocenecarboamide hexyl, or carbohydrate-propyl azides by using click chemistry (CuAAC) to afford polyconjugated oligonucleotides. Conjugations were performed either in solution
制备了三种具有两种或三种炔烃功能的新型亚磷酰胺,并将其引入寡核苷酸的 5' 端。通过使用点击化学 (CuAAC) 将得到的双和三炔寡核苷酸与乙酰硫代己基、二茂铁碳酰胺己基或碳水化合物-丙基叠氮化物缀合以提供多缀合寡核苷酸。结合在溶液中或在固体支持物上进行,效率很高。
