| titleOfInvention | Production of optically active alpha-amino-epsilon-caprolactam |
| abstract | PURPOSE: To obtain the titled compound in high yield and optical purity with simple procedure, by carrying out the optical resolution of DL-α-amino-ε- caprolactam using an optically active N-benzoyl-methionine as an optical resolution agent. n CONSTITUTION: 1mol of DL-α-amino-ε-caprolactam (abbreviated as DL-ACL) is made to contact with 0.1W2.0mol of N-benzoyl-L-methionine and N-benzoyl-D- methionine used as an optical resolution agent at 0W80°C preferably in water. A hardly soluble diastereomer salt is crystallized from the resultant solution e.g. by cooling the solution. The salt is separated by a solid-liquid separation process such as filtration, centrifugal separation, etc., and is subjected to optical resolution e.g. by contacting with a cation exchange resin in an aqueous solvent. The resolution agent is separated and the cation exchange resin is eluted with NH 3 , etc., to obtain D-ACL or L-ACL. n USE: Intermediate for L-lysine or raw material of pharmaceuticals such as hypotensor. n COPYRIGHT: (C)1987,JPO&Japio |
