A facile and direct oxidative reaction for the synthesis of vicinaltricarbonyl amides in moderate to excellent yields (53–88%) was developed starting from readily available β-ketoamides in the presence of phenyliodine(III) bis(trifluoroacetate). The resulting products possess significant synthetic potential, making this approach a valuable addition to the group of traditional methods already available

and efficient one-potsynthesis of functionalized [1,8]naphthyridine derivatives via a three-component domino reaction of glutaraldehyde, malononitrile, and β-ketoamides, undercatalyst-freeconditions in an environmentally friendly medium (ethanol) is described. The main advantages of this protocol are short reaction times, practical simplicity, high yields, catalyst-freeconditions, cheap and benign
