The invention concerns perfluoro-lower-alkyl derivatives of amino acids. A new synthetic route is provided for preparing .alpha.-aminotrifluoromethylketones, by converting .alpha.-amino acids to oxazolidin-5-ones which are then reacted with Ruppert's Reagent. Fluorinated derivatives of amino acids and peptides are shown to have a new property of inhibiting or inactivating metallo-.beta.-lactamase enzymes, and are thus valuable components of antibacterial formulations. Certain of the trifluoromethyl derivatives of amino acids are new compounds per se.

Sodium salts of aryl imines of glycine and phenylalanine react with nitrosonium tetrafluoroborate in acetonitrile to yield 3-nitroso-2-aryl-5-oxazolidones and those of β-alanine give 3-nitroso-2-aryl-6-oxotetrahydro-oxazines.
