Facile Synthesis of Some New Dihydropyrazole Derivatives from 3-(Sub-stituted)-n-Phenyl-2-Enamides under the Framework of Green Chemistry

Urvashi Tiwari and Pinki B. Punjabi

The present work reports MW assist ed synthesis of dihydropyrazoles (5a-5e) by cyclocondensation of 3-(substituted)-N-phenyl-2-en amide (3a-3e) with the hydrazide derivatives of benzotriazole (4) in presence of glacial acetic acid (GAA). The s ynthesized compounds have been characterized by their IR, 1 H NMR and Mass spectral studies.
