Electrochemical Trifluoromethylation/Spirocyclization of N-Benzylacrylamides to Construct Trifluoromethylated 2-Azaspiro[4.5]decanes
An electrochemical trifluoromethylation/spirocyclization of N-benzylacrylamides with CF3SO2Na as the source of trifluoromethyl group has been developed.This approach is carried out in a simple undivided cell at room temperature without relying on metal-reagents and oxidants,which provides a green and efficient route to construct a series of CF3-containing 2-azaspiro[4.5]decanes.Furthermore,the gram-scale synthesis and transformation can be easily performed.
