radical acylation of imines with α-ketoacids has been achieved, enabled by an electron-donor–acceptor (EDA) complex. This EDA complex-mediated process eradicates the use of a photocatalyst. Visible light is used as the sole promoter for this reaction, and CO2 is the only side product. Substrates with amide, cyanide, ester, ether, halides, and heterocycles were compatible. This radical acylation allows
通过电子给体-受体(EDA)配合物,实现了可见光诱导的亚胺与α-酮酸的自由基酰化反应。该EDA络合物介导的过程消除了光催化剂的使用。可见光被用作该反应的唯一促进剂,而CO 2是唯一的副产物。具有酰胺,氰化物,酯,醚,卤化物和杂环的底物是相容的。这种自由基酰化作用可以高达90%的分离产率获得结构多样的α-氨基酮(32个实例)。
