Convenient approach for the synthesis of previously unknown 7H-pyrano[2,3-d]isoxazol-7-one core was elaborated. The presented method is based on two stage process including preparation of diketone monoximes and their subsequent intramolecular dehydration. It was shown that among various dehydrating agents the best results were achieved using system TsCl/Et3N. The advantages of the considered procedure are easily available starting compounds, simple experimental procedure and isolation of the final products, avoiding column chromatography.
