Process for the preparation of (r)- or (s)-aminocarnitine inner salt, the salts and derivatives thereof |
摘要 |
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.
