A photoredox-assisted reductive acyl cross-coupling reaction of two different carboxylic acid esters was developed for ketone synthesis. The reaction proceeded smoothly under mild conditions using Hantzsch ester (HE) as an organic reductant, with high chemoselectivity and functional group compatibility. A large range of aryl and 1°, 2°, 3°-acyl electrophiles, and 1°, 2°, 3°-alkyl radical precursors
开发了两种不同羧酸酯的光氧化还原辅助还原酰基交叉偶联反应用于酮合成。以Hantzsch酯(HE)为有机还原剂,反应在温和条件下顺利进行,具有较高的化学选择性和官能团相容性。允许使用大范围的芳基和 1°、2°、3°-酰基亲电试剂,以及 1°、2°、3°-烷基自由基前体。
