A series of 5,5‐diarylhydantoin (Dilantin) 3, 4, and 7, imidazole 1, 2, 5, 6, 8, and 9, thiazole 10–12, triazinthione 13, 15, 16, and 17, and thiadiazine 14 derivatives, containing diverse hydrophobic groups, were green synthesized through one‐pot stepwise reaction of aromatic aldehydes, vitamin B1, and nitrogen nucleophiles, for example, urea, thiourea, and thiosemicarbazide using grinding technique
一系列5,5- diarylhydantoin(大仑丁)的3,4,和7,咪唑1,2,5,6,8,和9,噻唑10 - 12,triazinthione 13,15,16,和17,和噻二嗪14使用研磨技术和常规热方法,通过芳香醛,维生素B1和氮亲核试剂(例如尿素,硫脲和硫代氨基脲)的一锅式逐步反应,绿色合成了包含各种疏水基团的衍生物。这种合成的化合物具有有效的杀虫活性。例如,化合物4,6,和17表现出对两者的最高杀虫活性小菜蛾和棉铃虫最小抑菌浓度为500μg/ mL,LD50活性为50μg/ mL。然后将密度泛函理论应用于探索这些化合物的结构和电子特性。所有合成的化合物均已根据其元素分析和光谱数据进行了表征。
