Benzohydrazide derivatives 1–43 were synthesized via “one-pot” reaction and structural characterization of these synthetic derivatives was carried out by different spectroscopic techniques such as 1H NMR and EI-MS. The synthetic molecules were evaluated for their in vitro urease inhibitory activity. All synthetic derivatives showed good inhibitory activities in the range of (IC50 = 0.87 ± 0.31–19.0 ± 0

Symmetric and unsymmetric 1,3,4-oxadiazoles were synthesized in situ from hydrazine hydrate and the corresponding 2-acyl-4,5-dichloropyridazin-3-ones as acylating agents in polyphosphoric acid or BF 3 OEt 2 in excellent yields.
