Abstract
A three-stage method was proposed for the synthesis of new 4-[4-(2-azolylethyl)piperazine-1-yl]-N-aryl-5H-1,2,3-dithiazole-5-imines. This approach includes the reaction of Appel salt with anilines to produce 1,2,3-dithiazole-5-imines, which were converted into 4-[(4-chloroethyl)piperazine-1-yl]-5H-1,2,3-dithiazole-5-imines, alkylating azoles at the final stage. The high fungicidal activity of target compounds and intermediate 4-chloro-N-aryl-1,2,3-dithiazole-5-imines was shown in vitro tests versus six species of phytopathogenic fungi.
摘要
提出了一种分三步合成新的 4-[4-(2-氮乙基)哌嗪-1-基]-N-芳基-5H-1,2,3-二噻唑-5-亚胺的方法。这种方法包括将阿佩尔盐与苯胺反应生成 1,2,3-二噻唑-5-亚胺,然后将其转化为 4-[(4-氯乙基)哌嗪-1-基]-5H-1,2,3-二噻唑-5-亚胺,并在最后阶段烷基化唑类化合物。体外测试表明,目标化合物和中间体 4-氯-N-芳基-1,2,3-二噻唑-5-亚胺对六种植物病原真菌具有很高的杀菌活性。
