A series of novel ethyl 4‐(methyl or trifluoromethyl)‐2‐(2‐(substituted phenoxy)acetamido)thiazole‐5‐carboxylates 7a, 7b, 7c, 7d, 7e and 8f, 8g, 8h, 8i, 8j, 8k, 8l, 8m, 8n, 8o, 8p, 8q, 8r were synthesized, and their structures were confirmed by IR, 1H‐NMR, MS spectra and elemental analysis. The results of preliminary bioassays show that some of the title compounds exhibit moderate to good herbicidal
一系列新型的4-(甲基或三氟甲基)-2-(2-(取代的苯氧基)乙酰氨基)噻唑-5-羧酸乙酯7a,7b,7c,7d,7e和8f,8g,8h,8i,8j,8k,8升,8米,8N,8O,8P,8Q,8R,合成,并通过IR,证实它们的结构1H-NMR,MS光谱和元素分析。初步生物测定的结果表明,某些标题化合物具有中等至良好的除草活性。与无氟化合物相比图7a,图7b,和图7e,轴承氟化合物8克,8J,和8Q显示出与针对70-100%抑制更高的除草活性荠菜,苋restroflexus,以及旱莲草,在150剂量g / ha,表明噻唑环上的三氟甲基对于除草活性是有益的。此外,化合物8f,8g,8H,8I,8J,8K,8升,8米,8N,8O,8P,8Q,8R中测试了杀真菌活性抗霜霉病在500微克/毫升。化合物8f和8q表现出最佳的杀真菌活性,且抑制率超过80%。
