Abstract:

Fourteen new 3-substituted-6-(4′-decarboxydehydroabietyl)-1,2,4-triazolo-[3,4-b]-1,3,4-thiadiazoles 5a~5e and 11a~11i were obtained from the reaction of 3-substituted-4-amino-5-mercapto-1,2,4-triazoles 4 and 10 with dehydroabietic acid ]1 in the presence of phosphorus oxychloride, respectively. All target compounds were characterized by IR, 1H NMR, 13C NMR and MS. The preliminary antibacterial activity assay showed that title compounds 5 and 11 exhibited a fungicidal activity against C.Albicans, E.coli., M.Luteus and S.Dysenteriae.

Key words: dehydroabietic acid, triazolo[3,4-b]-thiadiazole, antibacterial activity
