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.
