几种新型的3-取代苯基异恶唑衍生物是由取代的苯基-丁-1,3-二酮制备的。它们的结构通过元素分析、IR、MS和1H NMR得到证实。 X射线结构分析表明，化合物中苯环与异恶唑环的二面角分别为19.46°和49.18°。初步生物测定表明，标题化合物对多种杂草均具有良好的活性，与 。这与之前的研究不同，之前的研究表明苯环与杂环部分的大二面角对于高除草活性是必要的。 J.杂环化学，（2010）。
The several novel 3-substituted phenyl isoxazole derivatives were prepared from substituted phenyl-butan-1,3-dione. Their structures were confirmed by element analysis, IR, MS, and 1H NMR. X-ray structure analysis indicated that the dihedral angles of the phenyl ring with the isoxazole ring in compounds and were 19.46° and 49.18°, respectively. Preliminary bioassay showed that the title compounds had good activity to various weeds, and exhibited almost the same activity with . This was different from the former works, which showed that the big dihedral angle of the phenyl ring with the heterocyclic moiety was necessary for high-herbicidal activity. J.
