hymexazol, a commercially available agricultural fungicide, at the concentration of 50 μg/mL, two indole[1,2-c]-1,2,4-benzotriazines, 5h and 5k, exhibited the more promising and pronounced antifungal activities in vitro against five phytopathogenic fungi. It clearly demonstrated that introduction of appropriate substituents on the indolyl ring of indole[1,2-c]-1,2,4-benzotriazine (5a) would lead to
在叔丁基亚硝酸盐(t- BuONO)存在下,通过改良的Sandmeyer反应获得了一系列新型的吲哚[1,2 - c ] -1,2,4-苯并三嗪衍生物。与可商购的农用杀菌剂氨甲唑相比,其浓度为50μg/ mL时,两种吲哚[1,2 - c ] -1,2,4-苯并三嗪5h和5k表现出更有希望和更显着的抗真菌活性在体外对五种植物病原真菌的抵抗力。清楚地表明,在吲哚[1,2 - c ] -1,2,4-苯并三嗪(5a)的吲哚环上引入适当的取代基将导致更有效的衍生物。
