, p. 91 - 97 (2000)
A novel synthesis of N-arylsulfonylamino-2-pyridones via reaction of arylmethylenemalononitriles with cyanoacetyl-N-arylsulfonylhydrazides is reported and the synthetic potential of the method is demonstrated.
Regioselective synthesis of a new class of N-arylsulfonylaminated biheterocycles
Elgemeie, Galal Hamza,Sayed, Shahinaz Hassan
, p. 465 - 473 (2007/10/03)
A novel and efficient method for the synthesis of a new variety of novel N-arylsulfonylamino derivatives of biheterocycles by the reaction of N-cyanoaceto-arylsulphonylhydrazides with α,β-unsaturated nitriles. The synthetic potential of the method is demonstrated.
A new general method for substituted 4-alkylthio-N-arylsulphonyl-amino-2-pyridones: Reaction of ketene-ss-acetals with arylsulphonylhydrazides
Elgemeie, Galal H.,Ali, Hosny A.,Elghandour, Ahmed H.,Abdel-Aziz, Hassan M.
, p. 171 - 179 (2007/10/03)
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.
