Abstract
An electrochemical facilitated three-component trifluoromethylation/spirocyclization reaction of N-(arylsulfonyl)acrylamides, CF3SO2Na, and H2O has been developed. Without the requirement of chemical oxidants, a number of unexplored trifluoromethylated 4-azaspiro[4.5]decanes were obtained in satisfactory yields under mild conditions. This work provides a new synthetic strategy for fluorine-containing spirocyclic compounds and shows a new perspective for the reactivity study of N-(arylsulfonyl)acrylamides.
