C., and then concentrated to dryness. When the obtained aminonitrile compound is hydrolyzed using acid or alkali,
2-amino-4-(hydroxy)phosphinoylbutyric acid is obtained. In addition, a reaction system of 3-oxopropylphosphinic acid represented by the formula [] and sodium cyanide or potassium cyanide/ammonium carbonate, or cyanic acid/ammonium carbonate, etc.
The reaction was carried out at a temperature of 80°C for 1 to 5 hours with stirring, and the following formula [] 2-(hydroxyphosphinoyl) represented by
By obtaining ethyl-5-hydantoin and further hydrolyzing this compound using acid or alkali, the following formula [] It is possible to obtain 2-amino-4-(hydroxy)phosphinoylbutyric acid represented by Synthesis of 2-acylamino-4-(hydroxy)phosphinoylbutyric acid The following formula [] (In the formula, R has 1 to 1 carbon atoms, such as a methyl group, an ethyl group, a propyl group, a butyl group, a pentyl group, etc.)
Represents a linear or branched lower alkyl group having 5 alkyl groups. ) 2-acylamino-4-(hydroxy)phosphinoylbutyric acid represented by the formula [] is prepared by adding 2-amino-4-(hydroxy)phosphinoylbutyric acid represented by the formula [] in the presence of a base according to a conventional method.
It is easily prepared by reacting acid anhydrides or acid chlorides. These compounds further include 2-amino-4-
It is also useful as an additional culture substrate in the production of SF-1293 substance (Japanese Patent Application Laid-Open No. 1983-67026), which has strong herbicidal activity like (hydroxy)(methyl)phosphinoylbutyric acid, by culture conversion. That is, a SF-1293 substance producing bacterium, for example, Streptomyces hygroscopicus strain SF-1293 (Japanese Patent Publication No. 51-639) or its mutant strain is cultured in a nutrient medium, and then a predetermined amount of 2- Amino-4
-(Hydroxy)phosphinoylbutyric acid or its N
When the -acyl derivatives are added and the culture is continued, these compounds are quickly incorporated into the SF-1293 substance, increasing the production amount of the SF-1293 substance. In the following, the present invention will be explained in more detail with reference to Examples. Example 1 Sodium hypophosphite hydrate 5.3g, acrolein dimethyl acetal 5.1g, 2,2-bis(t

Next, this reaction solution was concentrated to dryness under reduced pressure, then dissolved in 300 ml of water, and applied to a 1R-120B (H + ) column (100 ml). Additionally, 200 ml of water was passed through the column. These passed through liquids and washing liquids were combined and concentrated to dryness, and then recrystallized from an ethanol-acetone system to obtain DL-2-acetylamino-4.
1.2 g of white crystalline powder of -(hydroxy)phosphinoylbutyric acid was obtained. Elemental analysis values; C: 34.38, H: 5.72, N: 6.59, O: 38.33%. Theoretical values as molecular formula C 6 H 12 NO 5 P: C: 34.46, H: 5.78, N: 6.70, O: 38.25%. NMR (CD 3 OD) δppm; 1.60−2.20 (4H, m, P

-(Hydroxy)phosphinoylbutyric acid and 2-acetylamino-4-(hydroxy)phosphinoylbutyric acid were added at the concentrations and times shown in the table. After making the culture solution acidic, centrifugation (3000 rpm, 15
The supernatant was obtained using an amino acid analyzer (manufactured by ATTO, MLC-703 model, retention time 14 minutes).
The production amount of 1293 substances was measured. The results are shown in the table. [Table] As is clear from the table, it was confirmed that the production amount of SF-1293 substance was increased by adding the phosphinic acid derivative of the present invention. (Effects of the Invention) According to the present invention, 2-amino-4-(hydroxy)(methyl)phosphinoylbutyric acid useful as a herbicide and an antifungal agent can be easily and inexpensively produced. (Hydroxy)(methyl)phosphinoylbutyric acid intermediates can be provided.
