ABSTRACT:
The (R) or (S) isomer of acetorphan or N-/2-acetylthiomethyl)-1-oxo-3-phenylpropyl/(S) alanine methyl ester is prepared by splitting of racemic acetylthio-2-benzylpropanoic acid by reaction with ephedrin, separation of the enantiomeric salt obtained, then freeing of the acid and coupling with the corresponding amino acid ester. The obtained preparations possess remarkable therapeutic activities and can notably be used as drugs.
