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 1 H‐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] 25 D=−31.3° ( c = 10, H 2 O).
