The diastereoselective synthesis via Grignard reaction of enantiopure analgesic naphthylaminoalcohols has been performed. The chiral racemic key intermediate 3‐dimethylamino‐2‐methyl‐1‐(naphthalen‐2‐yl)propan‐1‐one and enantiomers were prepared and transformed into the desired compounds by addition of the organometallic reagent. The chemical characterization of all diastereoisomers was accomplished by 1 H NMR and HPLC analyses and the absolute configuration assigned by CD spectroscopy. The in vitro and in vivo profile has also been evaluated. Chirality 2006. © 2006 Wiley‐Liss, Inc.
