  • Enzymatic synthesis of chiral amines using -2-amino propane as amine donor
    Patent number: 6133018
    Abstract: 2-Aminopropane is used as the amine donor in the stereoselective synthesis of a chiral amine from a ketone with a transaminase. In a typical embodiment, (S)-1-methoxy-2-aminopropane is prepared by bringing methoxyacetone into contact with a transaminase in the presence of 2-aminopropane as an amine donor until a substantial amount of methoxyacetone is converted to (S)-1-methoxy-2-aminopropane and 2-aminopropane is converted to acetone. In a second embodiment, L-alanine is prepared by bringing pyruvic acid into contact with a transaminase in the presence of 2-aminopropane as an amine donor.
