A series of 2‐substituted phenoxy‐N‐(4‐substituted phenyl‐5‐(1H‐1,2,4‐triazol‐1‐yl)thiazole‐2‐yl)acetamide derivatives 8a, 8b, 8c, 8d, 8e, 8f, 8g, 8h, 8i, 8j, 8k, 8l, 8m, 8n, 8o, 8p, 8q, 8r, 8s, 8t was synthesized by the reaction of phenoxyacetyl chloride 7 with intermediate 4‐substituted phenyl‐5‐(1H‐1,2,4‐triazol‐1‐yl)thiazol‐2‐amine 5. Their structures were confirmed by 1H NMR, 13C NMR, MS, IR,
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
