Abstract:

Seven novel 1,2,4-triazole derivatives containing thioether and thiazole were designed and synthesized from ethyl 4,4,4-trifluoro-3-oxobutanoate, sulfonyl chloride, hydrazine hydrate, phenyl isothiocyanate, aryl iodides, chloroacetic acid as starting materials via substitution, hydrazinolysis, cyclization and Ullmann coupling. The structures of these compounds were characterized with 13C NMR, 1H NMR, 19F NMR and MS. Bactericidal activity test shows that Rhizoctoniasolani can be inhibited by compounds 6b, 6d, and 6g at a concentration of 100 mg/L with inhibition rates of 91%, 92% and 93%, respectively.

 

Key words: thioether, thiazole, triazole, synthesis, bioactivity
