Popis: A method for the synthesis of substituted 4-(het)aryl-4-oxo-2-thienylaminobut-2-enoic acids containing a nitrile substituent in the thiophene ring was proposed. Intramolecular cyclization of the obtained compounds in the presence of propionic anhydride leads to the formation of new substituted 3-thienylimino-3H-furan-2-ones.
