| Abstract | ||
| Starting compound 4-(furan-2-yl)-but-3-en-2-one(aliphatic ketone) has been prepared by treating furfuraldehyde with acetone, which reacted with diethylmalate to give diketo ester(1), then converted (1) to corresponding pyrazole derivative(2) by reacted with (2, 4-dinitro phenyl hydrazine). Pyrazole derivative (2) reaction with hydrazine hydrate to gives acid hydrazide (3), then reaction of (3) with aldehydes (benzaldeyde) to yield Schiff base (4) and with ketones (acetopenone) to yield Schiff base (5). Schiff base (4) converted into oxadiazole cyclic (6) by reacted with acetic anhydride. | ||
