Syntheses of 3-(3-Acetyl-5-aroxymethylene-2,3-dihydro-1,3,4-oxadiazol-2-yl) Chromones
Abstract:
Reactions of 4 substituted 3-formyl chromones with 4 aroacetohydrazides,catalyzed by ice acetic acid,gave 16 corresponding Schiff Base compounds.Then 3-(3-acetyl-5-aroxymethylene-2,3-dihydro-1,3,4-oxadiazol-2-yl) chromones were prepared by heating and refluxing the Schiff base with Ac2O.All the target compounds were characterized by means of elemental analysis,IR,LC-MS,and 1H NMR.
