A synthetic protocol based on Cp*Co-catalyzed C-H amidation/annulation of 2-aryl-1-imidazoles with 1,4,2-dioxazol-5-ones was developed to give imidazo[1,2-]quinazoline derivatives with broad substrate scope in moderate to good yields. The method has good prospects of application in the synthesis of imidazo[1,2-]quinazoline drugs.
开发了一种基于 Cp*Co 催化的 2-芳基-1-咪唑与 1,4,2-二恶唑-5-酮的 C-H 酰胺化/环化的合成方案，以中等至良好的收率得到具有广泛底物范围的咪唑并[1,2-a]喹唑啉衍生物。该方法在合成咪唑并[1,2-a]喹唑啉药物方面具有广阔的应用前景。
