Title (EN) PROCESS FOR THE PRODUCTION OF D,L-2-AMINO-4-METHYLSULPHOSPHINO-BUTYRIC ACID
(FR) PROCEDE DE PRODUCTION D"ACIDE D, L-2-AMINO-4-METHYLSULPHOSPHINO-BUTYRIQUE
Abstract: front page image
(EN)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.
(FR)Un procede de production d"acide D, L-2-amino-4-methylsulphosphino-butyrique ayant a la fois des activites herbicide et fongicide, dans lequel dialkylmethylphosphonite reagit avec de l"acroleine pour faire la synthese d"un acetal d"un ester acide 3-oxopropylmethylphosphinique; la composition est soumise a une desacetalisation pour obtenir un ester acide 3-oxopropylmethylphosphonique et a une reaction Strecker pour la synthese d"un amino acide.
