A silver-catalyzed efficient and practical synthesis of 3-acyl-4-arylquinolin-2(1H)-ones or 3-acyl-4-aryldihydroquinolin-2(1H)-ones through intermolecular radical addition/cyclization in aqueous solution is reported. This method provides a novel, highly efficient, and straightforward route to substituted quinolin-2-ones or 3,4-dihydroquinolin-2-ones in one step. A possible mechanism for the formation

A novel route toward 3,4-disubstituted dihydroquinolin-2(1H)-ones viaradical process has been developed in aqueous solution without metals. This method offers a new and simple route for the synthesis of skeleton of dihydroquinolin-2(1H)-one in one step.
