PHOSPHORUS SULFUR AND SILICON AND THE RELATED ELEMENTS
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-Arylsulfonylam
ino-pyrazolo[3,4-c]pyridine-2(1H)-ones have also been prepared from the rea
ction of 4-alkylthio-N-arylsulfonylamino-2-pyridones with hydrazines.
