  Synthesis and Herbicidal Activities of 4-Substituted 3-Aryl-5-tert-butyl-4-oxazolin-2-ones

  摘要：

  A series of novel 3-aryl-5-tert-butyl-4-chloro-4-oxazolin-2 (16) have been prepared and found to show significant herbicidal activity in the grams per are range against broadleaf and narrowleaf weeds. The key step in the introduction of the chlorine atom at the 4-position of the 4-chloro-4-oxazolin-2-one ring is dichlorination using chlorine gas and subsequent dehydrochlorination using diazabicyclo[5.4.0]undecene. 4-Alkylthio- and 4-methyl-4-oxazolin-2-one rings were synthesized from alpha-substituted alpha-bromopinacolone by cyclization reaction. Among the synthesized compounds, 5-tert-butyl-4-chloro-3-[4-chloro-2-fluoro-5-(2-propynyloxy)phenyl]-4-oxazolin-2-one (16h) showed the greatest activity against several weeds without damage to transplanted rice in the paddy field.

  A benzene derivative substituted with a heterocyclic ring represented by the general formula: ##STR1## wherein R represents a cycloalkyl group having 3 to 8 carbon atoms, X represents a halogen atom, and Z represents ##STR2## in which said cycloalkyl group may be substituted with an alkyl group having 1 to 6 carbon atoms, a process for preparing the same, and a herbicidal agent comprising the above compound as an active ingredient are disclosed. The compound has an excellent effect in that the compound exhibits a markedly high herbicidal effect on weeds in the field and the paddy field at a low dose and yet exhibits markedly low noxious effects on main crops.

  本发明涉及一种苯环衍生物，其被杂环环代替，通式如下：##STR1## 其中，R代表3至8个碳原子的环烷基团，X代表卤素原子，Z代表##STR2## 在该环烷基团可以被1至6个碳原子的烷基团取代的情况下，揭示了制备该化合物的过程以及以该化合物为活性成分的除草剂。该化合物具有显著的优点，即在低剂量下，该化合物对田间和稻田中的杂草表现出显著的高除草效果，同时对主要作物表现出显著的低有害作用。

  A heterocycle-substituted benzene derivative represented by general formula (I) wherein R represents C₃ to C₈ cycloalkyl, X represents halogen, and Z represents (Ia) or (Ib) provided that the cycloalkyl may be substituted with C₁ to C₆ alkyl. This compound is excellent in that it has a remarkably high herbicidal effect against weeds growing in both upland and lowland fields in a low dose, while it has a remarkably low phytotoxicity against main crops.

  一种杂环取代的苯衍生物，由通式(I)表示，其中 R 代表 C₃ 至 C₈ 环烷基，X 代表卤素，Z 代表(Ia)或(Ib)，但环烷基可被 C₁ 至 C₆ 烷基取代。这种化合物的优异之处在于，它对生长在高地和低地的杂草都有显著的高剂量除草效果，而对主要作物的植物毒性却很低。
