Page/Page column 9, (2008/06/13)
The present invention relates to a process for the resolution of derivatives of α-amino acids. In particular the process is concerned with the resolution of a mixture of enantiomers of N-protected amino acids by crystallisation with enantiomerically pure N-unprotected β-amino acid derivatives.
