A series of 1,3,4‐oxadiazolyl‐quinazolin‐4(3H)ones have been synthesized using known methods. All the compounds have been established on basis of elemental analysis, IR and NMR spectral data. The in vitro antimicrobial screening of the synthesized compounds were carried out against two gram‐positive bacteria (S. aureus, S. pyogenes), two gram‐negative bacteria (E. coli, P. aeruginosa), and three fungal
Three series of substituted1,3,4-oxadiazoles were studied by (17)O NMR spectroscopy. Chemical shifts values were correlated with empirical Hammett parameters as well as calculated bond lengths and chemical shielding values.
