A facile synthesis of 5-(perfluoroalkyl)-pyrimidines+
Humboldt-University Berlin, Department of Chemistry 104 Berlin, GDR
Received October 15, 1975.
In the paper a synthetic two stage procedure is described for the preparation of perfluoroalkylated derivatives of uracil and its nucleosides. Using copper bronze a perfluoroalkyl-copper-complex is formed from perfluoroalkyliodides in polar aprotic solvents, such as DMSO, and under inert conditions. The reaction of this complex with uracil, uridine and 2'-deoxyuridine leads to the corresponding 5-substituted perfluoroalkyl derivatives. It is shown by mass spectra that the substitution always takes place at the 5-position of the pyrimidine. The chemical and physical properties of the formed compounds are described.
