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 EC95 of 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.

Key words: Dipyrimidinone diphenyl ether, 4, 4'-Diformyl diphenylether, Biginelli reaction
