1-(3-quinolyl)-3,4-dihydroisoquinoline derivatives of formula (I) as well as a method of combating, preventing or controlling the phytopathogens Mycosphaerella graminicola (Septoria tritici), Fusarium culmorum, Gibberella zeae (Fusarium graminearum) and Monographella nivalis (Microdochium nivale), which comprises applying to the phytopathogen, to the locus of the phytopathogen, or to a plant susceptible to attack by the phytopathogen, or to propagation material thereof, a fungicidally effective amount of a 1-(3-quinolyl)-3,4-dihydroisoquinoline derivative of formula (I). The present description discloses the synthesis of exemplary compounds, formulation examples, relevant biological data (antifungal activity against Mycosphaerella graminicola (Septoria tritici), Fusarium culmorum, Gibberella zeae (Fusarium graminearum) and Monographella nivalis (Microdochium nivale) when spayed on plants), as well as comparative data against three prior art compounds (e.g. pages 52 to 85; formulation examples; examples A1 to A3; table E; compounds E.01 to E.187; biological examples). Exemplary compounds are e.g.: 5-bromo-1-(8-fluoro-3-quinolyl)spiro[4H-isoquinoline-3,1'- cyclopropane] (example A1) 5-bromo-1-(8-fluoro-3-quinolyl)-3,3-dimethyl-4H-isoquinoline (example A2) 1-(8-fluoro-3-quinolyl)-3,3-dimethyl-4H-isoquinoline-5-carbonitrile (example A3)
1-(3-喹啉基)-3,4-二氢异喹啉衍生物的化学式(I),以及一种用于对抗、预防或控制植物病原体Mycosphaerella graminicola (小麦丝孢菌), Fusarium culmorum, Gibberella zeae (玉米赤霉菌) 和 Monographella nivalis (雪腐病菌) 的方法,包括向植物病原体、植物病原体的生长部位,或易受植物病原体侵袭的植物,或其繁殖材料施加具有杀菌效果的1-(3-喹啉基)-3,4-二氢异喹啉衍生物的有效量。本描述披露了示例化合物的合成、配方示例、相关生物数据(在植物上喷洒后对Mycosphaerella graminicola (小麦丝孢菌), Fusarium culmorum, Gibberella zeae (玉米赤霉菌) 和 Monographella nivalis (雪腐病菌) 的抗真菌活性),以及与三种先前技术的化合物的比较数据(例如第52至85页;配方示例;示例A1至A3;表E;化合物E.01至E.187;生物学示例)。示例化合物包括:5-溴-1-(8-氟-3-喹啉基)螺[4H-异喹啉-3,1'-环丙烷](示例A1)、5-溴-1-(8-氟-3-喹啉基)-3,3-二甲基-4H-异喹啉(示例A2)、1-(8-氟-3-喹啉基)-3,3-二甲基-4H-异喹啉-5-碳腈(示例A3)。
