ABSTRACT: A palladium-catalyzed efficient synthesis of  5-methylisoxazoles via oxime-mediated functionalization of unactivated  olefins is described. The reaction affords a variety of  5-methylisoxazoles in moderate to good yields. To further demonstrate  the utility of the method, the rapid synthesis of valdecoxib and  oxacillin is reported.
