Synthesis and Antifungal Activity of Some Novel 1-Phenyl-3-methyl-4-substituted phenyl-6-imino-4,7- dihydro-1,3-thiazino(5,4-d)pyrazoles

Abstract

1-Phenyl-3-methyl-4-substituted phenyl-6-imino-4, 7-dihydro-1,3-thiazino(5,4-d)pyrazoles (3) have been synthesized by the reaction of 1-phenyl-4-arylidene-3-methyl pyrazolo-5-ones (2) and thiourea in methanolic KOH. The synthesized compounds have been screened for their antifungal activity against P. graminis tritici and P. recondita.
