The title compounds (3g–n) and (6g–n) were synthesized using 3-arylsydnones as synthons, and the structures were confirmed by IR, 1 H NMR, FAB mass and CHN analysis. These compounds were evaluated for their antibacterial and the antifungal activities in terms of minimum inhibitory concentrations (MICs) against the bacterial strains E. coli, B. cereus, and the fungal strains A. niger, C. albicans. Some of the compounds have shown significant activities.
