Title:
光学活性な3-アミノカルボン酸エステルの製造方法
Document Type and Number:
Japanese Patent JP5566103
Kind Code:
B2
Abstract:
The invention relates to a method for producing optically active 3-aminocarboxylic acid ester compounds. According to said method, an enantiomer mixture of a mono-N-acylated 3-aminocarboxylic acid ester, which mixture was previously enriched in an enantiomer, is subjected to deacylation and then to a further enantiomer enrichment by crystallization by adding an acidic salt-forming substance.
