Abstract: A process is disclosed for the stereo-selective preparation of emtricitabine, which allows the desired product to be obtained in good yield and without the use of chromatographic techniques. The process for the production of emtricitabine of the formula (Ia) is characterized by the formation and isolation of intermediate compounds of formula (XIa) in salified form. Emtricitabine is a known antiviral drug.
