A copper(I)-catalyzed, regioselective C-H alpha-trifluoromethylation of alpha,beta-unsaturated carbonyl compounds using Togni's reagent was developed. Diverse substrates, including enones as well as alpha,beta-unsaturated esters, thioesters, and amides, stereospecifically afforded the corresponding (E)-alpha-trifluoromethylated products in moderate to high yields. Further, this method was applied to the C-H trifluoromethylation of drugs.
