Synthesis, Crystal Structure, and Antibacterial Activity of 1,2,4-Triazoles and 1,2,4-Triazol-3-one
摘要:
A straightforward method has been developed for the synthesis of 1,2,4-triazol-3-one 3 and 1,2,4-triazoles 6a, 6b, 6c, 6d starting from N-1-substituted-N-1-tosylhydrazonates 2 and hydrazine monohydrate. This methodology affords a number of 1,2,4-triazol-3-one 3 and 1,2,4-triazoles 6a, 6b, 6c, 6d in reasonable yields. The structures of all new compounds were elucidated using infrared, H-1 and C-13 NMR, high-resolution mass spectrometry, elemental analysis, and the X-ray crystallography (for compounds 3 and 6a). Some of the newly synthesized compounds were screened for their antibacterial activity.

Abstract A series of Amidrazones, Triazoles, Thiatriazole and Triazine derivatives was synthesized, and their antibacterial and antioxidant activities were evaluated. Biological screening showed that the majority of the compounds possess a moderate antibacterial activity and a significant antioxidant effects. In order to further research the compound 3a, the crystal structure was detected by X-ray diffraction
