Terephthalaldehyde: An Effecient Key Precursor for Novel Synthesis of Some Interesting Bis-thiazoles and Bis-triazolopyrimidinones

Novel bis-thiazoles were synthesized in high and efficient yields from the reaction of thiosemicarbazones with halogenated compounds. Also, new bis-triazolopyrimidines were prepared from the reaction of hydrazonoyl chlorides with bis-thione derivative. All prepared compounds were fully characterized by spectral methods. The synthesized bis-compounds will be attractive species for the medicinal researchers to investigate their biological activity.
