METHOD FOR RESOLVING ENANTIOMERS FROM RACEMIC MIXTURE HAVING CHIRAL CARBON IN ALPHA POSITION OF NITROGEN

摘要

Disclosed relates to a simplified method for resolving enantiomers by dissolving a racemic mixture having chiral carbon in a-position of nitrogen and an amino acid to prepare a diastereomeric salt, not using catalyses or enzymes, with enhancing the optical purity remarkably. Moreover, the present invention can prepare the enantiomers in large quantities without using expensive catalysts or without controlling the reaction conditions for the activity of enzymes applied.
