Abstract
The present invention relates to the processes of racemization and deprotection of special N-protected amino acids in the acylase/racemase system for the total conversion of special N-protected racemic amino acids into optically pure amino acids.
Claims19
A process for preparing amino acids, comprising contacting a compound of the general formula (I):
- wherein
- X=O, NH,
- R1=CH3, CH3CH2, tert-butyl, benzyl, wherein if X is NH then R1 may additionally be H,
- and R2 denotes the α-radical of a natural or synthetic amino acid, with an N-acetylamino acid racemase and an amino acid acylase;
- and
- recovering the amino acids produced.
