Seven different chalcones I(a)-I(g) were synthesised by literature method from 2-hydroxy-5-methyl acetophenone. They were reacted with hydroxyl-amine hydrochloride in pyridine to get seven 3-(2-hydroxy-5-methylphenyl)-5,5-dialkyl/5,5-diaryl/5-aryl-isoxazolines II(a)-II(g). The structures of these compounds were confirmed on the basis of chemical and spectral analysis.
