ligand-free, Pd(OAc)2-catalyzed, three-component reaction for the synthesis of 2,3-diarylimidazo[1,2-a]pyridines was developed under microwave irradiation. With the high availability of commercial reagents and great efficiency in expanding molecule diversity, this methodology is superior to the existing procedures for the synthesis of 2,3-diarylimidazo[1,2-a]pyridines analogues.
在微波辐射下,开发了一种快速的单锅、无配体、Pd(OAc) 2催化的三组分反应,用于合成 2,3-二芳基咪唑并[1,2- a ]吡啶。由于商业试剂的高可用性和扩展分子多样性的高效率,该方法优于现有的合成 2,3-二芳基咪唑并[1,2- a ]吡啶类似物的方法。
