[FR] L'invention concerne un procédé destiné à la préparation énantiosélective d'un sel d'acétate d'ester de méthyle de (2R,3S)-3-phénylisosérine représenté par la formule générale (I). Ce sel est un motif structural utile dans la synthèse de dérivés de taxane. Le procédé comprend la résolution d'un amide de thréo-phénylisosérine racémique et sa conversion pour obtenir la formule générale (I).
