A palladium-catalyzed practical and efficient method to access alkoxycarbonylated imidazo[1,2-a]pyridines at the C-3 position has been developed based on the association of W(CO)6 as a safe and easy-to-handle CO surrogate and related alcohols. Through this synthetic strategy, a wide range of alkoxycarbonylated imidazo[1,2-a]pyridines with moderate to high yields have been prepared, which are important
基于 W(CO) 6作为安全且易于处理的 CO 替代物的结合,开发了一种钯催化的实用且有效的方法来获取C-3 位的烷氧基羰基化咪唑并 [1,2- a ] 吡啶和相关的酒精。通过这种合成策略,已经制备了多种具有中等至高产率的烷氧基羰基化咪唑并[1,2- a ]吡啶,它们是医药产品中的重要结构基序。
