The prevalence of 1,3-dipolar cycloadditions of azides and alkynes within both biology and chemistry highlights the utility of these reactions. However, the use of a copper catalyst can be prohibitive to some applications. Consequently, we have optimized a copper-free microwave-assisted reaction to alleviate the necessity for the copper catalyst. A small array of triazoles was prepared to examine the
在生物学和化学领域中,叠氮化物和炔烃的1,3-偶极环加成反应的普遍性突出了这些反应的效用。但是,铜催化剂的使用对于某些应用可能是禁止的。因此,我们优化了无铜微波辅助反应,以减轻铜催化剂的必要性。制备了一小批三唑来检验这种方法的范围,并将该方法通过使用非天然氨基酸转化为蛋白质,以证明涉及全长蛋白质的首批微波介导的生物缀合物之一。
