An efficient newsynthesis of 3,5-bis(het)arylisoxazoles, involving the reaction of 1,3-bis(het)arylmonothio-1,3-diketones with sodiumazide in the presence of IBX catalyst, has been reported. The reaction proceeds at room temperature in high yields and is applicable to a broad range of substrates including the synthesis of 5-methyl-3-arylisoxazoles, a key subunit present in several β-lactamase-resistant
