Abstract In order to find new compounds with high fungicidal activity, acetamide derivatives 4a–x were rationally designed, synthesized, characterized and tested against various fungi in vivo. The bioassay results indicate that compounds 4k,m,o,r exhibit an 80% inhibition rate against Rhizoctonia solani at 500 mg/L, and compound 4j shows an 80% inhibition rate against Blumeria graminis at 500 mg/L
摘要 为了寻找具有高杀菌活性的新化合物,乙酰胺衍生物 4a-x 被合理设计、合成、表征并在体内对各种真菌进行了测试。生物测定结果表明,化合物4k,m,o,r 在500 mg/L 时对立枯丝核菌具有80% 的抑制率,化合物4j 在500 mg/L 时对禾本科植物的抑制率为80%。因此,4的化合物是值得进一步开发的有前途的杀真菌候选物。
