    摘要: 2-Amino-4-(hydroxy)(methyl)phosphinoylbutyric acid, which earlier nomenclature referred to as 2-amino-4-methylphosphinobutyric acid or its metal salts, or acid-addition salts thereof are used as perennial weeds and brush controlling agents. The L-isomer is twice effective than the racemic acid. The perennial weeds and brush controlling effect may be obtained by foliar application over a prolonged period and maY be surprisingly enhanced by using the compound with a herbicide or synergist selected from the group consisting of choline salt of maleic hydrazide, a phenoxy series herbicide, a benzoic acid series herbicide, 2,3,6-trichlorophenylacetic acid or a salt thereof, (3,5,6-trichloro-2-pyridyl)oxyacetic acid or a salt thereof, N-phosphonomethylglycine or a salt thereof, ethylcarbamoylphosphoric acid or a salt thereof, 2-(1-allyloxyaminobutylidene)-5,5-dimethyl-4-methoxycarbonyl-cyclohexane-1,3-dione, 3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea,3-amino-1,2,4-triazole, choline or a salt thereof, and diethylamine or a salt thereof.

    摘要: PCT No. PCT/JP78/00058 Sec. 371 Date June 15, 1979 Sec. 102(e) Date June 15, 1979 PCT Field Dec. 18, 1978 PCT Pub. No. WO79/00405 PCT Pub. Date July 12, 1979This invention relates to a novel process for preparing D,L-2-amino-4-methylphosphinobutyric acid having herbicidal and antifungicidal activities which comprises subjecting acrolein to reaction with a dialkyl phosphonite to synthesize an acetal of an ester of 3-oxopropylmethylphosphinic acid; treating the thus obtained compound with an acid for deacetalization to obtain an ester of 3-oxopropylmethylphosphinic acid and then applying the Strecker's process used for amino synthesis to the thus obtained ester.
