A sustainable and cost‐effective protocol for direct aminomethylation of imidazo‐fused heterocycles by decarboxylative coupling reaction of N‐phenylglycines with imidazo‐fused heterocycles in the presence of CsPbBr3 under the irradiation of visible light has been developed. This is the first example of CsPbBr3‐catalyzed aminomethylation of imidazo‐fused heterocycles. The eminent advantage of this...
A metal‐free visible‐light‐induced cyclization procedure was developed for the rapid synthesis of perfluoroalkyl‐substituted benzimidazo[2,1‐a]isoquinolin‐6(5H)‐ones and perfluoroalkyl‐substituted indolo[2,1‐a]isoquinolin‐6(5H)‐ones under mild reaction conditions. In this procedure, the formation of electron‐donor‐acceptor (EDA) complex is critical for the visible‐light promoted process to avoid the...
A convenient radical cascade cyclization of aniline‐linked 1,7‐enynes with 1,3‐dicarbonyl compounds was developed to synthesize cyclopenta[c]quinolines in the presence of AgNO3/K2S2O8. A wide range of cyclopenta[c]quinolines were prepared in moderate to excellent yields.
A transition‐metal‐free visible‐light‐promoted radical phosphorylation/cyclization of N‐allylbenzamides with phosphine oxides for the synthesis of phosphoryl‐substituted dihydroisoquinolones was developed under room temperature. This protocol features mild reaction conditions, simple operation, broad substrate scope as well as scale‐up ability.
