| Abstract: | A new route to L-carnitine ( 1 ) based on the resolution of th trimethylammonium derivative 5 is described. The enantiomeric purity of 1 is determined by 1H-NMR of its O-acetyl hydrochloride 11 using Eu(hfc)3] as chiral shift reagent. The optical rotation of 1 with an enantiomeric purity ≥99% is α] =?31.3° (c = 10, H2O). |
