- Abstract
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 H 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.
