| titleOfInvention | Method for preparing 3- (substitutedphenyl) -5-alkylidene-1,3-oxazolidine-2,4-dione derivative |
| abstract | The present invention provides an industrial preparation for efficiently synthesizing 3-substituted phenyl-5-isopropylidene-1,3-oxazolidine-2,4-dione derivatives having strong herbicidal activity without using phosgene or the like. to provide.n n n That is, N-substituted phenylcarbamic acid ester represented by the following general formula (I), 2-hydroxy-3-alkene ester represented by the following general formula (II), or 3-alkoxy-2 represented by the following general formula (IV) It relates to a method for producing a 3-substituted phenyl-5-alkylidene-1,3-oxazolidine-2,4-dione derivative represented by the general formula (III), by reacting a -hydroxyalkanoic acid ester.n n n n n n n n (Wherein Ar represents a substituted phenyl group, R 1 represents an alkyl group having 1 to 6 carbon atoms, R 2 and R 3 independently represent a hydrogen atom or an alkyl group having 1 to 12 carbon atoms, and R 4 and R 5 are independent) To alkyl groups having 1 to 6 carbon atoms). |
