Synthesis and Characterization of New 2-Oxo-azetidine Derivatives
摘要:
Several new N-[(4-aryl-3-chloro-2-oxo-azetidine)acetamidyl]-5-nitroindazoles 4a-l were synthesized from N-(arylidene amino acetamidyl)-5-nitroindazoles 3a-l. The structures of all these compounds were confirmed by infrared, H-1 NMR, C-13 NMR, and fast atom bombardment-mass spectra and also by microanalytical data.

Conventional and microwave assisted synthesis of Some new N-[(4-oxo-2-substituted aryl −1, 3-thiazolidine)-acetamidyl]-5-nitroindazoles and its antimicrobial activity
Several new N-[(4-oxo-2-substituted aryl-1, 3-thiazolidine)-acetamidyl]-5-nitroindazoles (4a-1) were synthesized from N-(arylidene amino acetamidyl)-5-nitroindazoles (3a-1). The reactions were carried out by both conventional as well as microwave method. The structures of these compounds were confirmed by IR, H-1 NMR, C-13 NMR, FAB-mass spectra and also by microanalytical data. The newly synthesized compounds were evaluated for their antimicrobial activity against variety of bacterial and fungal strains. The compounds 4g and 4h showed the maximum antibacterial activity (MIC 11 and 10 mu g/mL) against Escherichia coli and antifungal activity (MIC 9 and 8 mu g/mL) against Fusarium oxysporum.
