Some peculiar features of two most commonly used catalytic systems (Cul and CuSOVsodium ascorbate) controlling the regioselectivity of 1,3-dipolar cycloaddition of azides to terminal alkynes have been studied. Their potentialities, main disadvantages, and limitations have been demonstrated by a number of examples, including reactions of low-molecular-weight azides and alkynes containing heterocyclic
研究了两种最常用的催化系统(Cul和CuSOV抗坏血酸钠)控制叠氮化物与末端炔烃的1,3-偶极环加成反应的区域选择性的某些特殊功能。通过许多实例证明了它们的潜力,主要缺点和局限性,包括低分子量叠氮化物和含有杂环取代基的炔烃的反应。讨论了在点击反应中使用新型试剂的可能性。
