Novel trisubstituted pyrido[3,2-e][1,2,4]triazines have been found to possess similar biological activity to the corresponding pyridopyrazine fungicides against important phytopathogens such as Mycosphaerella graminicola (wheat leaf blotch), Magnaporthe grisea (rice blast), and Rhizoctonia solani (rice sheath blight). They have been prepared for the first time from a monocyclic triazine by Niementowski-type
已发现新型三取代的吡啶并[3,2- e ] [1,2,4]三嗪具有与相应的吡并吡嗪杀真菌剂相似的针对重要植物病原体的生物学活性,例如重要的致病性小麦霉菌(Mycosphaerella graminicola)(小麦叶片斑点病),稻瘟病菌(Magnaporthe grisea)(稻瘟病)。以及茄枯萎病(Rhizoctonia solani)。它们是由Niementowski型环缩合首次由单环三嗪制备的。
