一系列2-取代的苯氧基-N-(4-取代的苯基5-(1 H -1,2,4-三唑-1-基)噻唑-2-基)乙酰胺衍生物8a,8b,8c,8d,通过苯氧乙酰氯7反应合成8e,8f,8g,8h,8i,8j,8k,8l,8m,8n,8o,8p,8q,8r,8s,8t。与中间体4-取代的苯基-5-(1 H -1,2,4-三唑-1-基)噻唑-2-胺5。它们的结构通过1 H NMR,13 C NMR,MS,IR和元素分析确认。还筛选了合成化合物对三种植物真菌(赤霉菌,疫霉疫霉和萨氏副伤寒)和两种细菌的抑菌活性(Xanthomonas oryzae pv。)。米(Xoo)和黄单胞菌(Xanthomonas axonopodis)。citri(Xac)]显示出可喜的结果。尤其是,8b,8f,8g和8h对Xoo表现出优异的抗菌活性,其50%有效浓度(EC 50)值分别为35.2、80.1、62.5和82.1 µg
Fifteen novelcompounds bearing the triazole moiety were synthesized and structurally characterized. The title compounds showed some antimycotic and plant growth regulating activities, especially in the case of 4d and 4c. The latter compound affected also the liver cancer 7402 cell viability.
