title: Copper-catalyzed arylsulfonylation of N-arylsulfonyl-acrylamides with arylsulfonohydrazides: synthesis of sulfonated oxindoles.
abstract: A copper-catalyzed arylsulfonylation of N-arylsulfonyl-acrylamides with sulfonylhydrazides through a tandem radical process was developed. This methodology provided an alternative strategy for the synthesis of sulfonated oxindoles by forming C-S, C-N and C-C bonds in a single operation.
