In recent times, allenes have attracted the interest of many chemists due to their unique structural and electronic features as highly valuable synthetic precursors in preparative organic chemistry. Special attention has been given to transition-metal-catalyzed hydrofunctionalizations of allenes with the view to the selective formation of the C−N bond. On the other hand, it is well known that the selective incorporation of fluorine functionalities, into specific positions of organic molecules can substantially alter their chemical and physical properties and thereby has become an essential tool in the drug discovery process. Continuing our investigations in the development of new methodologies for the synthesis of trifluoromethylated alfa-amino acids and their phosphorous analogues we present an efficient approach to unsaturated alfa-CF3-alfa-ornithine derivatives and their phosphorus analogues by the copper-catalyzed interaction between CF3-containing allene systems and different primary and secondary amines
