Synthesis, antibacterial and surface activity of 1,2,4-triazole derivatives

چکیده
Sodium 1-[4-amino-5-mercapto-4H-(1,2,4)triazol-3-yl]heptadecane-1-sulfonate 2 has been used as a new precursor to synthesize some important biologically active heterocycles. Reaction of 2 with carbon disulphide in pyridine and acid chlorides yields the 1,2,4-triazole derivatives 3, 4a and 4b. Condensation of 2 with appropriate aldehydes gives 5a-c which have been cyclized by treating with thioglycollic acid to yield 6a-c. Reactions of 2 with phthalic anhydride and 4methylbenzenesulfonyl chloride gives 7 and 8. In addition, the reaction of 2 with chloroacetaldehyde, phenacyl bromide, urea and chloroacetyl chloride yields 9, 10, 11 and 12, respectively. On the other hand, refluxing 2 with phenyl isothiocyanate gives 13 and 14. All these products have antimicrobial activity and they can be used as surface active agents.
