A process for the production of (R)— or (S)-aminocarnitine starting respectively from (R)— or (S)-nitryloxycarnitine, through the formation and hydrogenation of the azidocarnitine intermediate with the same absolute configuration is described. (R)— aminocarnitine inner salt is obtained after purification, which is then converted into non-deliquescent salts. A further subject of the present invention is a process for the preparation of derivatives of (R)— and (S)-aminocarnitine, in particular acylated or ureic derivatives, having known pharmacological properties, starting from (R)— and (S)-aminocarnitine salts, releasing the aminic function in situ.
