The base-catalysed addition of acetylacetone to 3-methyl-4-nitro-5-styrylisoxazoles (II) leads to the Michael adducts 3-pentane-2,4-diones (III).These β-diketones (III) undergo cyclization with hydrazine sulphate and phenylhydrazine to furnish pyrazoles (IV) and N-phenylpyrazoles (V), respectively.
