N-substituted 2-imino-5-aryl-2,3-dihydro-3-furanones are produced during the thermal decarbonylation of 5-aryl-2,3-dihydro-2,3-furandiones in the presence of isocyanides.Primary and secondary amines open the ring in the products, leaidng to the formation of the amides of N-substituted 4-amino-4-aryl-2-oxo-3-butenoic acids.The acid hydrolysis of N-substituted 2-imino-5-aryl-2,3-dihydro-3-furanones leads to the corresponding amides of 4-aryl-2,4-dioxybutaric acids.
