【摘要】 以3,4-亚甲二氧基苯酚和1-H-1,2,4-三唑为主要原料,合成了12种1-[(6-烷(苄)氧基-3,4-亚甲二氧基)苯基]-2-(1H-1,2,4-三唑)-乙酮(醇)类化合物。化合物经IR、1H NMR1、3C NMR、元素分析测试技术进行了表征确证。初步生物测试结果表明,在质量浓度为1×10-4g/mL下,化合物Ⅴc对小麦赤霉病菌的抑制率达81.3%;化合物Ⅳe对马铃薯干腐病菌的抑制率达83.4%;化合物Ⅴe、Ⅴf对玉米弯孢病菌的抑制率分别达79.7%和72.4%。更多还原

【Abstract】 In order to find novel low toxic and high-efficiency fungicides,12 1-[6-alkoxy(benzloxy)-3,4-methylenedioxyphenyl]-2-(1H-1,2,4-triazole-1-yl)-enthone(ol) compounds were prepared from sesamol and 1-H-1,2,4-triazole.The structures of all the synthesized compounds were confirmed by IR,1H NMR,13C NMR and elemental analysis.Preliminary bioassay tests showed that at a concentration of 1×10-4 g/mL,the inhibitory rate of compounds Ⅴc to Fusarium graminearum was 81.3%;that of Ⅳe to Fusarium oxysporium was 83.4%;those of Ⅴe and Ⅴf to Cercospora sorghi were 79.7% and 72.4% respectively.更多还原
