Abstract

Alok K. Pareek*, P. E. Joseph and Daya S. Seth

A Series of some new substituted pyrazolone derivatives containing different functional groups have been synthesized by the condensation reaction of 2-methoxy-5-methyl ethyl aceto hydrazone (1a) and different substituted phenyl malonamic acid hydrazides (2a-2k) in presence of glacial acetic acid as a catalyst, substituted isoxazolone (4a) have been synthesized by the condensation of 2-methoxy-5-methyl ethyl aceto hydrazone (1a) and hydroxylamine hydrochloride with sodium acetate. The constitution of the synthesized compounds are characterized by their elemental analysis, spectral studies like IR.
