New synthesis of enantiomerically pure (S)-3-amino-2-phenyl propanoic acid via the asymmetric transformation of its racemic N-phthaloyl derivative

Calmes, Monique,Escale, Francoise

, p. 2845 - 2850 (2007/10/03)

The synthesis of racemic N-phthalyl 3-amino-2-phenyl propanoic acid and its asymmetric transformation via the corresponding prochiral ketene have been investigated, allowing the preparation of enantiomerically pure (S)-3- amino-2-phenyl propanpic acid.
