    摘要: The present invention provides a process for producing isoxazole derivatives represented by the formula ##STR1## wherein R.sup.1 and R.sup.2 are the same or different and are each a hydrogen atom or lower alkoxyl, and R.sup.3 is cyano or alkoxycarbonyl, the process being characterized by oxidizing an .alpha., .beta.-unsaturated ketoxime derivative represented by the formula ##STR2## wherein R.sup.1 , R.sup.2 and R.sup.3 are as defined above. The isoxazole derivatives (II) to be produced by the process of the present invention are useful as intermediates for preparing (3,4-diarylisoxazol-5-yl) acetic acid derivatives which are useful as anti-inflammatory agents, analgesics and antipyretics.
