Title:
SMB-法を用いた、保護アミノ酸エナンチオマーのクロマトグラフィーによる分離
Document Type and Number:
Japanese Patent JP2005518338
Kind Code:
A
Abstract:
The present invention is directed to the separation of enantiomers of racemates of formula (I). The separation proceeds by applying deemed racemates to continuos enantioselective chromatography like SMB. The methods predominantly is performed for industrial scale production of pure enantiomers of deemed amino acids which are useful intermediates in organic synthesis.
