    摘要： PURPOSE: To profitably obtain the subject compound by optically resolving (RS)-1-(2,4-dichlorophenyl)ethylamine in the presence of a resolving agent comprising optically active aspartic acid which can be available in a relative low price in an industrial scale. CONSTITUTION: Optically active aspartic acid and (RS)-1-(2,4-dichlorophenyl) ethylamine are mixed with each other to form the salt. The optically active diastereomer salt is crystallized in a solvent, and subsequently isolated by a filtration method, etc. The salt is treated with a base to obtain the optically active 1-(2,4-dichlorophenyl)ethylamine. When the L-aspartic acid is used as the resolving agent, the product is R-(+). When the D-aspartic acid is used as the resolving agent, the product is S-(-). The compound obtained by the method is useful as an intermediate for producing optically active plant disease control agents or as an optically resolving agent. The aspartic acid used as the optically resolving agent can easily be recovered and further again used.

    摘要： PURPOSE:To obtain the new compound, having excellent herbicidal effects, excellent in selectivity between weeds of the family Polygonaceae or Portulacaceae and crops such as wheat or rice plant and useful as a herbicide. CONSTITUTION:This compound of formula I [R1 is a 1-6C (halo)alkyl, a 3-6C (halo)alkenyl, etc.; R2 is a 1-6C (halo)alkyl, a 3-7C (halo)cycloalkyl, etc.; R3 is H, a 1-6C (halo)alkyl, etc.; Q is a group of formula II [X is H, Cl or F; A is 0, S, etc.; R4 is a 1-6C (halo)alkyl, a 3-6C (halo)alkenyl, etc.], formula III {Y is Cl, F, Br, NO2 or CN; B is CO2R7 [R7 is H, a 1-10C (halo)alkyl, etc.}, etc.], e.g., a compound of formula IV. The compound of formula I is usually obtained by reacting a compound of the formula Q-NHC(=S)NH-R1 with a compound of the formula D1CH(R3)C(=O)R2 (D1 is Cl, Br or I) in a solvent.

    摘要： PURPOSE:To obtain a novel compound which is an important intermediate for producing a coumarin derivative useful as a herbicide. CONSTITUTION:This compound is expressed by formula I (R is a lower alkyl), e.g. 6-amino-7-fluoro-4-isopropyl-2H-benzopyran-2-one. The compound is obtained by reacting a compound expressed by formula II (e.g. 4-fluoro-2-hydroxy-2'- methylpropiophenone) with nitric acid in the presence a mineral acid such as sulfuric acid at -5 to +10 deg.C, nitrating the compound expressed by formula II, then reacting the resultant product with an alkoxymethyl chloride or an alkoxymethyl bromide in the presence of a base such as sodium hydride at 10-100 deg.C, providing a compound expressed by formula III (R' is an alkoxymethyl), subsequently reacting the prepared compound with a compound expressed by formula IV (R'' is an alkyl; R''' is a lower alkyl) (e.g. trimethyl phosphonoacetate) in the presence of a base such as n-butyl-lithium, then reducing the obtained product and finally cyclizing the resultant phenylpropionic acid ester derivative in the presence of an acid.

    摘要： PURPOSE:To provide a new compound having excellent controlling effect on plant blights, especially downy mildew and blast and useful as a fungicide agricultural and horticultural use. CONSTITUTION:The compound of formula I[R is cyano or thiocarbamoyl; Q is NQ Q (Q and Q are lower alkyl, lower alkynyl, etc.) or lower alkyl; X is H or halogen; Z is OCF2O, etc.]. The compound of formula I can be produced by reacting a 2-cyanobenzimidazole compound of formula II with a sulfonyl chloride derivative of the formula C1-SO2Q in the presence of a base (e.g. potassium carbonate) in a solvent (e.g. acetonitrile) at room temperature to refluxing temperature. The compound is useful as an agricultural and horticultural fungicide for plowed land, paddy field, orchard, tea plantation, pasture land, lawn, etc.

    摘要： PURPOSE:To provide a new compound exhibiting selectivity between crops and weeds and useful as an excellent herbicide. CONSTITUTION:The compound of formula I (R is H or methyl; R is alkyl or cycloalkyl; X is O or S). The compound can be produced by reacting a compound of formula II with a compound of formula NH2O-Y (Y is sulfonyl, 2,4-dinitrophenyl, etc.) in a solvent (e.g. DMF) in the presence of a base (e.g. sodium hydride) at -20 to +100 deg.C for 0.1-10hr. The starting compound of formula II is obtained by reacting a compound of formula III (R is lower alkyl) with a compound of formula TV (M is alkali metal; R is lower alkyl). The compound is effective for the control of various weeds which cause problems in the foliar treatment and soil treatment of plowed land and the water- treatment of paddy field.
