A new and efficient palladium-catalyzed amination of imidazo[2,1-b][1,3,4]thiadiazole at the C-5 position under microwave irradiation is reported. The reactivity toward bromine release at the C-5 position was investigated, and palladium-catalyzed cross-coupling conditions were optimized. A wide range of amines was employed to examine the scope and limitations of the method. To complete this methodological
报道了一种新的高效钯催化的咪唑并 [2,1-b][1,3,4] 噻二唑在微波辐射下的 C-5 位胺化。研究了 C-5 位溴释放的反应性,并优化了钯催化的交叉偶联条件。使用多种胺来检查该方法的范围和局限性。为了完成这项方法学研究,研究了额外的咪唑并 [2,1-b][1,3,4] 噻二唑取代的性质和位置的影响。
