Synthesis and antibacterial activity of novel series of 2-(p-tolyloxy)-3-(5-(pyridin-4-yl)-1,3,4-oxadiazol-2-yl)quinoline
摘要:
AbstractA new series of 2‐(p‐tolyloxy)‐3‐(5‐(pyridin‐4‐yl)‐1,3,4‐oxadiazol‐2‐yl)quinoline were synthesized from oxidative cyclization of N′‐((2‐(p‐tolyloxy)quinoline‐3‐yl)methylene)isonicotinohydrazide in DMSO/I2 at reflux condition for 3–4 h. The structures of the new compounds were confirmed by elemental analyses as well as IR, 1H‐NMR, and mass spectral data. All the synthesized compounds were screened for their antibacterial activities against various bacterial strains. Several of these compounds showed potential antibacterial activity. J.

A new series of 1-(5-(2-tolyloxyquinoline-3-yl)-2-(pyridine-4-yl)-1,3,4-oxidiazol-3(2H)-yl)ethanones were synthe- sized from cyclisation of N'-((2-(p-tolyloxy)quinoline-3-yl)methylene) isonitonohydrazide in acetic unhydride at reflux con- dition for 3-4 hr. The structures of the new compounds were confirmed by elemental analyses as well as IR, 1 H NMR and mass spectral data. All the synthesized compounds
