Abstract
AbstractA mild and efficient copper‐catalyzed intramolecular carbotrifluoromethylation of ene‐imines with Togni reagent as a trifluoromethylating reagent was realized. The reaction tolerates a range of substrates to give the corresponding 3‐trifluoroethylated 4‐amino‐chromans in moderate to good yields. A possible mechanism was proposed based on the experimental results.magnified image
