VERFAHREN ZUR HERSTELLUNG VON L-2-AMINO-4- (HYDROXYMETHYL-PHOSPHINYL)-BUTTERSÄURE.

摘要

A new process of producing L-2-amino-4-(hydroxymethylphosphinyl)-butyric acid (L-AMPB) is now provided, in which 4-(hydroxymethylphosphinyl)-2-oxo-butyric acid (OMPB) is treated with one or more transaminases or with one or more microorganisms capable of producing the transaminase, in the presence of one or more amino-donor compounds such as alpha -amino acids. According to this process, the optically active L-AMPB useful as herbicidal agent can be produced efficiently in a facile way for a reasonable reaction time.
