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.

Synthesis, Characterization and Antibacterial Activity of some Novel Thiosemicarbazides, 1,2,4-Triazol-3-thiols and their S-substituted Derivatives

The thiosemicarbazides 3a-c were appeared by reaction of the corresponding substituted hydrazides 1a-c with allylisothiocyanate 2. Synthesis of some novel 1,2,4-triazole-thiols 4a-c bearing a pyridyl unit using 1-(x-picolinoyl)-4-allyl-thiosemicarbazides (x = 2,3,4) in an alkaline solution, is reported. Also, the S-alkylation of triazole derivatives 5-7a-c is described. The structure of the syn...

Synthesis and Antimycobacterial Activity of some Triazole Derivatives–New Route to Functionalized Triazolopyridazines

A series of cyclic analogues of bioactive thiosemicarbazide derivatives have been synthesized as potential antimycobacterial agents. The 4-amino-1,2,4-triazole-5-thione analogues (Ia-f) were prepared by heating a mixture of thiocarbohydrzide and appropriate carboxylic acids. Reaction of thiocarbohydrazide with γ-ketoesters in the presence of sodium methoxide furnished triazolopyridazine derivat...
