A copper-mediated three-component approach towards the synthesis of 3-cyanoimidazo[1,2-a]pyridines from 2-aminopyridines, acetophenones and benzyl cyanide was developed. This cascade reaction proceeds through a copper-mediated oxidative release of cyanide from benzyl cyanide, a copper-mediated Ortoleva–King reaction, and a copper-catalyzed cyanation.
利用铜介导的三组分方法,从2-氨基吡啶、苯乙酮和苄基氰合成3-氰基咪唑[1,2-a]吡啶。这个级联反应通过铜介导的氧化释放苄基氰中的氰离子、铜介导的Ortoleva-King反应和铜催化的氰化反应进行。
