Abstract: The synthesis of condensed isoxazolines, containing an N-arylmaleinimide and an isoxazoline skeleton in the molecule is described. Thus the substituted 3, 5-diaryl-4, 6-dioxo-3a, 4, 6, 6a-tetrahydropyrrolo[3,4-d]-isoxazoles were synthesized by a 1, 3-dipolar cycloaddition of substituted benzonitrile oxides to substituted phenylmaleinimides, in which the substituent was H, Cl, F, Br, NO₂, OCH₃, CH₃, CH(CH₃)₂, CF₃, respectively. The prepared condensed isoxazolines were active against yeasts, moulds, and bacteria.
