2‐heteroatomthiazole‐based carboxanilides (8) are prepared by reacting 2‐heteroatomthiazole‐based carboxylic acid chlorides with 2,6‐dibromo‐4‐(trifluoromethoxy)aniline. The structures of all the newly synthesized compounds were supported by spectroscopic data NMR, MS, and elemental analysis, etc. Bioassay showed that the compounds exhibited potent fungicidal activities against Rhizoctonia solani,
通过使基于2-杂原子噻唑的羧酸氯与2,6-二溴-4-(三氟甲氧基)苯胺反应,制备了一系列新的基于2-杂原子噻唑的羧酰胺(8)。所有新合成的化合物的结构均通过光谱数据NMR,MS和元素分析等进行支持。生物测定表明,这些化合物显示出对茄红枯菌的有效杀真菌活性。特别是N-(2,6-dibromo-4 -(三氟甲氧基)苯基)-2-甲氧基-4-(三氟甲基)噻唑-5-羧酰胺(8a-2)的杀菌力与噻氟甲酰胺相当,后者是琥珀酸脱氢酶抑制剂(SDHI)的唯一商业化的噻唑甲酰苯胺杀菌剂。
