Fused heterocycles: Synthesis and fungistatic activity of some 1- aroyl/aryloxyaceto-4-aryl-5-cyano-3-methyl 1,4,5,6,7-pentahydropyrazolo[4,5- e]pyridin-6-ones and 1-aroyl/aryloxyaceto-4-aryl-3-methyl- 1,4- dihydropyrazolo[4,5-e]pyrido [ 1,2-α]pyrimidines

A number of 1-aroyl/aryloxyaceto-4-aryl-5-cyano-3-methyl 1,4,5,6,7- pentahydropyrazolo[4,5-e] pyridin-6-ones 3 and 1-aroyl/aryloxyaceto-4-aryl- 3-methyl-1,4-dihydropyrazolo[4,5-e]pyrido[1,2-α]pyrimidines 4 have been prepared by Michael addition between α,β-unsaturated ketones 2 and ethyl cyanoacetate/2-arninopyridine in the presence of ammonium acetate. These compounds have been evaluated for their fungistatic activity against P. oryzae, R. solani, P cubensis and P infestans.
