An efficient copper-catalyzed selective cross coupling of imidazo[1,2-a]pyridines with methyl hetarenes has been reported. This transformation opened a new route to synthesize the C-3 carbonyl imidazo[1,2-a]pyridine derivative, which is a common structural motif in natural products and pharmaceuticals. 18O-labeling experiments indicated that the oxygen source of products originated from O2.
已经报道了咪唑并[1,2- a ]吡啶与甲基己烯的有效铜催化选择性交叉偶联。这种转变为合成C-3羰基咪唑并[1,2- a ]吡啶衍生物开辟了一条新途径,该衍生物是天然产物和药物中常见的结构基序。18 O-标记实验表明产物的氧源来自O 2。
Pd-catalyzed oxidative cross-coupling of imidazo[1,2-a]pyridine with arenes
A facile method for direct Pd(OAc)2-catalyzed oxidative cross-coupling of unactivated imidazo[1,2-a]pyridine with simplearenes has been developed. The reaction shows good reaction efficiency, high regioselectivity, and good functional-group compatibility. This approach provides a useful protocol for the preparation of imidazo[1,2-a]pyridine–arene structure of interest in biological and pharmaceutical
已开发了一种简便的方法,用于未活化的咪唑并[1,2- a ]吡啶与简单的芳烃的直接Pd(OAc)2催化的氧化交叉偶联。该反应显示出良好的反应效率,高的区域选择性和良好的官能团相容性。该方法为生物和药物材料中感兴趣的咪唑并[1,2 - a ]吡啶-芳烃结构的制备提供了有用的方案。
