Title:
PROCESS FOR PREPARING OPTICALLY ACTIVE BETA-AMINOCARBOXYLIC ACIDS FROM RACEMIC N-ACYLATED BETA-AMINOCARBOXYLIC ACIDS
Document Type and Number:
WIPO Patent Application WO2003080854
Kind Code:
A3
Abstract:
A process is described for preparing optically active beta-aminocarboxylic acids from racemic N-acylated beta-aminocarboxylic acids by enantioselective hydrolysis of the N-acylated beta-aminocarboxylic acid in the presence of a hydrolase by way of biocatalyst, wherein the N-acyl substituent of the N-acylated beta-aminocarboxylic acid (I) exhibits Structure I in which R<1>, R<2> are each selected, independently of one another, from H, halogen, alkyl residues, OH, alkoxy residues and aryloxy residues; R<3> is selected from halogen, alkoxy residues and aryloxy residues; (II) Structure IIA or IIB or the structure of the corresponding salts or (III) Structure III or the structure of the corresponding salt.
