N-Sulfonylketenimines as Useful Synthons in a Novel Synthesis of Functionalized ۲-Oxoindoline Derivatives

The synthesis of a novel class of ۲-oxoindolin-۳-ylidene-(۱-arylhydrazinyl)-۲-aryl(alkyl)ethylidene derivativesvia a copper-catalyzed tandem reaction of isatin, arylhydrazines, sulfonyl azides and terminal alkynes is described.
