  • PROCESS FOR PRODUCTION OF OPTICALLY ACTIVE AMINE DERIVATIVE
    Publication number: 20110262977
    Abstract: Optically active amine derivatives are produced by acting on imine derivatives with a culture of microorganisms having the ability to stereoselectively reduce the compounds, microbial cells, or processed products thereof, followed by collecting the generated optically active amine derivatives. Optically active amine derivatives obtained in the present invention are useful as materials for pharmaceutical agents. The present invention enables, for example, production of an optically active compound represented by formula (IV): (wherein R group represents an alkyl group having one to three carbon atoms; and n represents an integer of 1 to 4).
