Alkylation of isomeric methyl nitropyrazolecarboxylates with bromoacetone followed by acid hydrolysis gave new N-acetonylnitropyrazolecarboxylic acids. A selectivesynthesis of 3-R-5-(N-acetonylnitropyrazolyl)-1,2,4-oxadiazoles based on the reaction of nitropyrazolecarboxylic acid chlorides with isomeric amidoximes of nitropyrazoles and aminofurazan was developed. The possibility to introduce the second
