of imidazo[1,2-a]pyridines via one pot three component reaction between 2-aminopyridine, aldehyde and terminal alkynes. The imidazo[1,2-a]pyridines are an imperative class of nitrogen ring containing heterocyclic compounds which has wide range of applications in medicinal chemistry and drug molecule production. The reported synthetic protocol provides a rapid access to substituted imidazo[1,2-a]pyridines
二维(2D)材料,例如石墨烯和功能化六方氮化硼(h-BN)负载的铜催化剂(CuO / rGO,CuO / h-BN,Cu(0)/ rGO,Cu(0)/ h-BN,CuS通过2-氨基吡啶,醛与末端炔烃的一锅三组分反应,制备了/ rGO和CuS / h-BN),表征并评估了它们对合成咪唑并[1,2- a ]吡啶的催化活性。咪唑并[1,2- a ]吡啶是一类必不可少的含氮环杂环化合物,在药物化学和药物分子生产中具有广泛的应用。报道的合成方案可快速获得取代的咪唑并[1,2- a吡啶具有优异的收率。发现CuO / rGO纳米复合材料是用于上述反应的高活性催化剂。与其他先前报道的方法相比,我们制备咪唑并[1,2- a ]吡啶的方法的优点包括反应时间短,官能团耐受性强,可循环使用的催化剂和无添加剂。
