A new general method for substituted 4-alkylthio-N-arylsulphonyl-amino-2-pyridones: Reaction of ketene-ss-acetals with arylsulphonylhydrazides

Article abstract of DOI:10.1080/10426500108040593

A novel and efficient method for the synthesis of substituted 4-alkylthio-N-arylsulphonylamino-2-pyridones via the reaction of ketene-SS-acetals with N-cyanoacetoarylsulfonyl-hydrazides has been investigated. 1-Arylsulfonylamino-pyrazolo[3,4-c]pyridine-2(1H)-ones have also been prepared from the reaction of 4-alkylthio-N-arylsulfonylamino-2-pyridones with hydrazines.
