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.
铜催化的通过串联自由基过程,N-芳磺酰基-
丙烯酰胺与磺酰
肼的芳基磺酰化反应被开发出来。这一方法学为通过单一操作形成C–S、C–N和C–C键,从而合成磺化
吲哚酮提供了替代策略。
