Synthesis and Characterization of Some New Schiff Base Containing 4, 5-Dihydroisoxazole Moieties

摘要

A series of Schiff bases combined with 4, 5-dihydroisoxazoele moieties as derivatives of chalcone were synthesized. Schiff base compounds containing chalcone group were prepared by the treatment of one mole of dicarbonyl compound, such as benzil, with one mole of different amine compounds and the products were reacted with acetone. The results were reacted with hydroxylamine hydrochloride in ethanol and glacial acetic acid as a catalyst for synthesis various derivatives of 4, 5-dihydroisoxazole moieties that combined with Schiff bases. The structures of the new synthesized compounds, Schiff bases combined with 4, 5-dihydroisoxazole moieties, have been established on the basis of their spectral data (FTIR, ~1HNMR, ~(13)CNMR and MASS).
