Novel Thienopyrimidine Derivatives Containing 1,2,4-triazoles and 1,3,4-oxadiazoles as Potent Antimicrobial Activity

Abstract

A series of thienopyrimidine oxadiazolederivatives (5a-l) were synthesized by cyclic condensation of substituted aroylhydrazides with triazole of carboxylic acid (4a-c). The synthesized compounds were characterized on the basis of their spectral (IR, 1H and 13C NMR) data and screened for antimicrobial activity where compounds 5b and 5d showed significant activity.
