direct modification of bioactive molecules in water. Through the combination of water‐compatible oxidative iodination and the copper‐catalyzed alkyne–azide cycloaddition reaction, a novel copper‐catalyzed aqueous multicomponent synthetic method for the preparation of 5‐iodo‐1,2,3‐triazoles has been developed. The method is highly effective and selective for substrates including biologically relevant
碘1,2,3-三唑在化学和生物医学应用中具有相当大的兴趣。然而,目前制备碘1,2,3-三唑的合成方法不能轻易地应用于水中生物活性分子的直接修饰。通过水相容性氧化碘化和铜催化的炔-叠氮化物环加成反应的结合,开发了一种新颖的铜催化的水性多组分合成方法,用于制备5-碘,1,2,3-三唑。该方法对包括具有核苷,糖和氨基酸部分的生物相关化合物的底物是高效和选择性的。基于这种水性串联反应,从容易获得的起始原料开发了直接的单步多组分双修饰肽。此外,由可商购获得的125碘化钠水溶液作为起始原料进行125 I标记。
