Incorporation of fluorine and fluorine containing groups such as trifluorom
ethyl and trifluoromethylthio moieties considerably enhances the biopharmac
ological properties of the parent precursors. Trifluoromethylsulfenylation
of masked carbonyl functions, such as the enamines using N-(trifluoromethyl
thio)phthalimide is described in this communication.
