摘要Abstract: 3-Arylsydnone-4-carbohydroximic acid chlorides could react with N-aryl- maleimides or 2-methyl-N-phenylmaleimide to give 3-(3-aryl-sydnon-4-yl)-5-aryl-3a,6a-dihydro-pyrrolo[3,4-d]isoxazole-4,6-diones or 6a-methyl-3-(3-arylsydnon -4-yl)-5-phenyl-3a,6a-dihydro-pyrrolo[3,4-d]isoxazole-4,6-diones . However, 3-(aryl- sydnon-4-yl)-naphtho[2,3-d]isoxazole-4,9-diones were obtained in good yield by the reaction of carbohydroximic acid chlorides 1 with [1,4] naphthoquinone. Furthermore, 2-(3-arylsydnon-4-yl)benzoxazoles and 2-(3-arylsydnon-4-yl)benzothiazoles were obtained via the reaction of carbohydroximic acid chlorides 1 with ortho substituted aromatic amines .
