Silver-catalyzed tandem radical acylarylation of cinnamamides in aqueous media†
Abstract
A mild silver-catalyzed regioselective radical addition/cyclization reaction of cinnamamides with α-oxocarboxylic acids has been developed. The procedure proceeded well under very mild conditions, leading to a diverse range of 3-acyl-4-aryldihydroquinolin-2(1H)-ones in moderate to good yields.
