A photochemical protocol for the synthesis of Weinreb amides and morpholine amides fromcarboxylicacids is presented. Various carboxylicacids were directly coupled to N,O-dimethylhydroxylamine and morpholine, upon irradiation with either LED 370 nm or sunlight in the presence of 4-dimethylaminopyridine and bromotrichloromethane, providing amides in moderate to high yields.
