Cyanuric fluoride-mediated fluorination of chiral N-alpha-tritylamino acids leads to the corresponding acyl fluorides which are powerful acylating agents for peptide synthesis. The acyl fluorides react with NaBH4, the stabilized phosphorane Ph3P=C(Me)CO2Me and Ruppert's reagent providing access to enantiomerically pure tritylamino alcohols, alkenes and trifluoromethyl ketones, respectively.
