The copper-catalyzed “click” reaction of an azide with an alkyne has become a popular method to build up 1,4-substituted 1H-1,2,3-triazoles in medicinal chemistry and this approach was used on a laboratory scale during the preparation of novel macrolide 1. However, the manufacture of the key azide component, as well as its subsequent use in the presence of a copper catalyst on a large scale, was associated
叠氮化物与炔烃的铜催化的“点击”反应已成为在药物化学中构建1,4-取代的1 H -1,2,3-三唑的流行方法,并且该方法在实验室规模内得到了应用。新型大环内酯类化合物的制备1。然而,关键叠氮化物组分的制造以及其随后在铜催化剂的存在下的大规模使用与潜在的安全隐患有关。因此,开发了一种序列,其中通过α,α-二氯甲苯磺酰基cyclo与胺的环缩合,完成了1,4-取代的1 H -1,2,3-三唑在1中的构建。
