Abstract:
PROBLEM TO BE SOLVED: To obtain the subject new compound useful for controlling harmful animals and harmful fungi. SOLUTION: This compound is shown by formula I Y is a halogen, a 1-4C alkyl or the like; (n) is 0-2; E is a group of formula II (V is O or the like); T is O or oxymethylene; Z is a group X [X is a (substituted) heterocyclyl, a (substituted) aryl or the like], N=CWR [W is a (substituted) 1-6C alkyl or the like; R is H, cyano or the like] or the like} such as N-methyl-5-[2-(o-tolyloxymethylene)phenyl]-1,3- oxazolidine-2,4-dione.The compound of formula I, for example, in the case in which it is a compound of formula III, is obtained by a process for acylating an alkyl α- hydroxy-α-phenylacetate with phosgene or the like to give a compound of formula IV and further reacting the compound with a primary amine of the formula H2 N-R αto cause a ring formation and in the case of not advancing the ring formation by the strength of the amine, by a process for hydrolyzing an ester amide of formula V, then treating the resultant substance with an acid and reacting the treated substance with a compound of the formula Z-OH.
Abstract:
PROBLEM TO BE SOLVED: To provide a compound that has increased controlling effect against harmful fungi. SOLUTION: The objective salicylic acid derivative is represented by formula I [wherein X is a halogen, NO2, cyano, an alkyl or an alkoxy; (m) is 0, 1, 2 or 3 where in the case m >=2, X may differ from each other; A is OH, an alkoxy, NH2, NHCH3 or N(CH3)2, R1 is phenyl, naphthyl, cycloalkyl, one to three N-atoms and/or one O or S atom or one or two O and/or S atoms- including 5-membered or 5-membered ring heteroaryl or 5-membered or 6-membered heterocyclyl where the ring structure may be unsubstituted or substituted; and R2 is H, cyano, an alkyl, an alkenyl, an alkynyl, a haloalkyl, an alkoxy or an alkylthio]. This invention further provides a method of producing the derivative, a composition including the derivative and the use of the composition for controlling harmful fungi.
Abstract:
PROBLEM TO BE SOLVED: To obtain the subject new compounds useful as intermediate compounds for the production of phenylacetic acid derivatives suitable as bactericides, effective for a wide variety of phytopathogens and usable also as leaf and soil disinfectants. SOLUTION: The objective compound is expressed by the formula R5ON=C (R4)-C(R3)=NOH [R3 is H, cyano, nitro, hydroxy, amino, a halogen, a 1-4C (halo)alkyl or the like; R4 is H, cyano, nitro, hydroxy, amino, a halogen, a 1-6C alkyl or the like; R5 is H, a 1-10C alkyl or the like], e.g. (E,E)-2- methoxyimino-2-[2'-(1"-methyl,1"-acetyl)-iminoxymethyl]phenylacetic acid methyl ester. The objective compound of the formula can be produced by reacting the corresponding hydroxyimine of the formula HON=C(R4)-C(R3)=NOH with a nucleophilically substituted reagent of the formula R5-L2 (L2 is a nucleophilic exchangeable eliminable group such as a halogen or sulfonate).
