| Abstract: | The treatment of chalcones 2a-f with substituted hydrazines in ethanol results
in the formation of 3-(3-aminonaphtho[2,1-b]fur-2-yl)-5-arylpyrazolines
3a-l.The reaction of these
chalcones 2a-f with hydroxylamine hydrochloride in
presence of catalytic amount of hydrochloric acid affords
3-(3-aminonaphtho[2,1-b]fur-2-yl)-5-arylisoxazolines
4a-f. The synthesis of another biheterocycle,
2-amino-3-cyano-4-aryl-6-(3-aminonaphtho[2,1-b]fur-2yl)pyridines 5a-f is accomplished by reacting
chalcones 2a-f with malanonitrile
in presence of ammonium acetate. All the newly synthesized compounds are
characterized by elemental analysis and spectral studies, and evaluated for
antimicrobial activity. |
