Abstract 4-Aryl-2-hydroxy-4-oxo-2-butenic (aroylpyruvic) acid arylamides react with triphenylphosphoranylidenacetic acid esters to form products of Wittig reaction at α-carbonyl group, the 5-aryl-3-arylaminocar-bonyl-5-oxo-3-pentenoic acid esters. Features in structure of the obtained compounds are discussed.
