2-Acetylthiophene condenses with different aromatic aldehyde in ethanol in the presence of aqueous NaOH to give 1-(2′thienyl)-3-(substituted phenyl)-2-propen-1-one(Ia-e) which reacts with hydroxylamine hydrochloride and aqueous KOH in presence of ethonal medium to give 3-(2′-thienyl)-5- (substituted phenyl)-2-isoxazoline (IIa-e). And 3-(2′-thienyl)- 5-(substituted phenyl)-Δ2-isoxazoline (IIa-e) was dissolved in DMSO. To this catalytic amount of iodine was added. Cooled and diluted with water. The solid thus separated was washed with 20% sodium thiosulphate to give 3-(2′-thienyl)-5-(substituted phenyl)-isoxazole (II′a-e). Characterization and structural elucidation were done on the basis of melting points determination, analytical and spectral studies.
