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。
