Synthesis and bioactivity of novel bis-heterocyclic compounds containing pyrazole and oxadiazoline

Nucleophilic addition of the starting material 3-aryl-1-phenyl-4- formylpyrazoles (1～3) and 4-substi-tuted aryloxyacetyl hydrazine (4a～4e) afford hydrazone compounds containg pyrazolyl (5a～5e, 6a～6e, 7a～7e) in the ethanol. These adducts were refluxed in A
