efficient method for the synthesis of a new variety of nitroso-N-arylsulfonylaminated pyridones and nitroso-N-substitutedamino pyridones via the reaction of oximederivatives of β-diketones and β-ketoesters with N-cyanoacetoarylsulfonylhydrazides and substituted cyanoacetohydrazides has been investigated. The synthetic potential of the method is demonstrated.
