摘要：
The present invention provides an industrial process for efficiently preparing a 3-(substituted phenyl)-5-isopropylidene-1,3-oxazolidine-2,4-dione derivative having a potent herbicidal activity without using phosgene or the like. The present invention relates to a process for preparing a 3-(substituted phenyl)-5-alkylidene-1,3-oxazolidine-2,4-dione derivative represented by general formula (III), which comprises reaction of an N-(substituted phenyl)carbamate represented by general formula (I) with a 2-hydroxy-3-alkenoate represented by general formula (II) or with a 3-alkoxy-2-hydroxyalkanoate represented by general formula (IV): (wherein Ar is a substituted phenyl group, R is an alkyl group having a carbon number of from 1 to 6, R and R are independently hydrogen atoms or alkyl groups having carbon numbers of from 1 to 12, and R and R are independently alkyl groups having carbon numbers of from 1 to 6).
摘要（中）：
本发明提供了一种不使用光气等有效制备具有强除草活性的3-（取代苯基）-5-异亚丙基-1,3-恶唑烷-2,4-二酮衍生物的工业方法。 本发明涉及制备通式（III）代表的3-（取代苯基）-5-亚烷基-1,3-恶唑烷-2,4-二酮衍生物的方法，该方法包括使N-（取代的 苯基）氨基甲酸酯与通式（II）代表的2-羟基-3-链烯酸酯或与通式（IV）代表的3-烷氧基-2-羟基链烷酸酯反应：＆lt; CHEM＆gt; （其中Ar为取代的苯基，R 1为碳数为1至6的烷基，R 2和R 3独立地为氢原子或碳数为1至100的烷基 12，并且R 4和R 5独立地为碳数为1至6的烷基）。
