  Spiroisoxazole and spiropyrazole derivatives were obtained in a four-component reaction of active isoxazol- or pyrazol-5-ones with aromatic aldehydes, phenacyl chloride and AcOH-AcONH4 mixture. The reaction sequence is highly chemo- and ­diastereoselective affording good yields of spiroisoxazoles in refluxing ethanol, while efficient formation of spiropyrazoles is closely related to the use of a microwave-assisted protocol.
