Abstract

An Efficient Synthesis of Isoxazoles and Pyrazoles under Ultrasound Irradiation. -A series of 5-arylisoxazole (II) and related pyrazole derivatives (III) are synthesized via ultrasound assisted reactions of 3-aminopropenone (I) with hydroxylamine or hydrazine hydrate, respectively. -(HUANG, Z.-B.; LI, L.-L.; ZHAO, Y.-W.; WANG, H.-Y.; SHI*, D.-Q.; J.
