Abstract

Atma Ram Mishra*, Vivek Srivastava and Abu Shahma

The new cis-3,3a-imidazo[2,1-a]-pyrazolo[3,4-d] thiazoles (IIa-l) have been synthesized by refluxing a mixture of 2-(p-ethoxy arylidene-5,6-dehydro imidazo [2,1-a]-thiazolidene-3-one(IIa-f) with hydrazine hydrate or 2,4-di-nitro phenyl hydrazine and anhydrous sodiumacetate in glacial acetatic acid. All the synthesized compounds have been characterized by elemental analysis & spectral data and also screened for their fungicidal activity against two fungal species that is Alternaria solanai & Puccinia recondita. Screening data have been co-related with the structural feature of the tested compounds.
