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 4a and 4b were 19.46° and 49.18°, respectively. Preliminary bioassay showed that the title compounds had good activity to various weeds, and 4a exhibited almost the same activity with 4b. This was different
几种新颖的3-取代的苯基异恶唑衍生物是由取代的苯基-丁丹-1,3-二酮制得的。通过元素分析,IR,MS和1 H NMR确认了它们的结构。X射线结构分析表明,化合物4a和4b中苯环与异恶唑环的二面角分别为19.46°和49.18°。初步的生物分析表明,标题化合物对各种杂草均具有良好的活性,而4a的活性几乎与4b相同。这与以前的研究不同,后者表明具有杂环部分的苯环的大二面角对于高除草活性是必需的。J.杂环化学。(2010)。
