Condensation of 2,4-diacetylphenol (I) with substituted benzaldehydes give 2,4-bis(substituted cinnamoyl)phenols (IIIa-c) which on treatment with hydrazine hydrate in acetic or formic acid furnish the corresponding 2,4-bis(1-acetyl/formyl-4,5-dihydro-5-arylpyrazol-3-yl)phenols (Va-f).Alkylation of I, IIIa-c and Va-c with ethyl chloroacetate gives the corresponding ethyl substituted phenoxyacetates (II, IVa-c and VIa-c).Treatment of VIa-c with hydrazine hydrate in ethanol affords the corresponding hydrazides VIIa-c.None of the compounds tested shows any in vitro growth inhibitory activity against Alternaria alternata, Macrophomina phaseolina, Helminthosporium oryzae and Fusarium oxysporum upto a concentration of 100 μg/ml.
