摘要
Mercapto benzoxazole reacted with alkyl halide or N-substituted-2-chloroacetamides gave corresponding 2-alkylthiobenzoxazoles(2a～2h) and benzoxazole-2-ylthio-acetanilides (3a～3g) respectively. The structures of all the above compounds were confirmed by 1H NMR, IR and elemental analysis. Results showed that only compound 2g exhibited favorable fungicidal activity against Puccinia triticina(90%) in vivo at dosage of 500 mg/L; compounds 3a～3g exhibited inhibitory activity to Echinochloa oryzicola V and Brassica campestris L at the dosage of 150 mg/m 2.
