摘要:
A method for efficiently producing L-2-amino-4-(hydroxymethylphosphinyl)-butanoic acid, useful as a herbicide, by a catalytic asymmetric synthesis reaction with a high asymmetric yield. The method includes a step in which a compound represented by the below formula (1) and a benzylamine are reacted in the presence of dehydrating agent, then the resulting mass is reacted with hydrogen cyanide in the presence of an asymmetric catalyst, followed by acid hydrolysis, further followed by elimination of a protective group. [chemical formula 1] (1) (where, R1 represents a C1-4 alkyl group.)
