A photoredox-catalyzed decarboxylative α-monofluoroalkylation of silyl enol ethers with fluoroalkyl carboxylic N-(hydroxy)phthalimide esters has been successfully developed. Diverse functionalized α-monofluoroalkyl acetophenones were produced in modest to good yields under mild and operationally simple conditions. The developed method was further applied to synthesize antalgic and ataractic activity
成功开发了硅烯醇醚与氟烷基羧酸N-(羟基)邻苯二甲酰亚胺酯的光氧化还原催化脱羧α-单氟烷基化反应。在温和且操作简单的条件下,可以以中等至良好的产率生产多种官能化的α-单氟烷基苯乙酮。该方法进一步应用于合成含有α-单氟烷基苯乙酮骨架的镇痛、镇静活性化合物。
