A process for the production of D,L-2-amino-4-methylsulphosphino-butyric acid having both herbicidic and fungicidic activities, in which dialkylmethylphosphonite is reacted with acrolein to synthesize an acetal of 3-oxopropylmethylphosphinic acid ester, the compound is subjected to deacetalization to obtain 3-oxopropylmethylphosphinic acid ester and then Strecker reaction for the synthesis of an amino acid is effected. |
