A series of 4-arylmethylidene-3-methyl-4,5-dihydroisoxazol-5-one derivatives were synthesized by the condensation reactions of aromatic aldehydes with 3-methyl-4,5-dihydroisoxazol-5-one via room temperature grinding or heating under solvent-free conditions without any catalyst. The products were identified by 1H NMR, IR, MS spectra and elemental analysis.

Key words: 4-arylmethylidene-3-methyl-4,5-dihydroisoxazol-5-one, condensation, ethyl acetoacetate, hydroxylamine hydrochloride, solvent-free, aromatic aldehyde, 3-methyl-4,5-dihydroisoxazol-5-one
