The reaction of enamine compounds with the Togni reagent in the presence of CuI afforded β-trifluoromethylated enamine intermediates, which were converted directly to biologically interesting trifluoromethylated 2-azirines by an iodosobenzene (PhIO)-mediated intramolecular azirination in a one-pot process.
