Abstract:

Generally, many diphenyl ethers show good bioactivity, the advances of these kind of compounds in medical area have made the synthesis research becoming a hot topic. In this work, through the Biginelli’s condensation of 4,4'-diformyl diphenylethers, β-ketoesters and urea catalyzed by FeC1₃·6H₂O, 12 novel dipyrimidinone diphenyl ethers were synthesized. The synthesis mechanism of dipyrimidinone was discussed and the reaction conditions were optimized. In the meantime, the synthetic method of 4,4'-diformyl diphenyl ether derivatives was also improved. Due to the appropriate timing of the reactants and catalyst's addition, this method had the advantage of short reaction time and excellent yields(90%). Finally, the preliminary toxicity testing of all the target compounds was investigated.The results showed that EC₉₅of compounds 6d, 6h and 6i were smaller than the comparison compound to Fusarium oxysporium f.s.p. niveum. The compounds containing R²(CF₃) had better biological acitivity than the others.
