The invention provides a method of combating fungus at a locus which comprises treating the locus with a compound of the general formula
or an N-alkyl or N-phenyl halide or N-oxide thereof, in which R¹, R², R³ and R⁴ independently represent a hydrogen or halogen atom, a hydroxyl group or an optionally substituted alkyl or alkoxy group, or R¹ and R² or R² and R³ or R³ and R⁴ together with the interjacent carbon atoms represent a 5- to 7-membered saturated or unsaturated carbocyclic or heterocyclic ring in which a heterocyclic ring contains 1 to 3 heteroatoms selected from nitrogen, oxygen and sulphur atoms; R⁵ represents a hydrogen or halogen atom, R⁶ represents a hydrogen atom, or R⁵ and R⁶ together represent a single carbon- carbon bond; R⁷ represents a hydrogen or halogen atom, an alkyl or alkoxy group optionally substituted by one or more halogen atoms, or an optionally substituted phenyl or phenoxy group; R⁸ and R⁹ independently represent a hydrogen atom or together represent a single carbon-carbon bond; and A represents an optionally substituted phenyl group. Certain of the isoquinoline derivatives are novel and a process for the preparation of these compounds and compositions containing them are also provided.
该发明提供了一种用于在一个位点上对抗真菌的方法,该方法包括使用通式的化合物或其N-烷基或N-苯基卤化物或N-氧化物处理该位点,其中R¹、R²、R³和R⁴独立地代表氢或卤素原子、羟基或可选择地取代的烷基或烷氧基,或者R¹和R²或R²和R³或R³和R⁴与介在碳原子之间形成一个含有1到3个来自氮、氧和
硫原子的杂原子的5-至7-成员饱和或不饱和碳环或杂环的环;R⁵代表氢或卤素原子,R⁶代表氢原子,或者R⁵和R⁶一起代表一个单一的碳-碳键;R⁷代表氢或卤素原子,一个烷基或烷氧基,可选择地取代一个或多个卤素原子,或者一个可选择地取代的苯基或苯氧基;R⁸和R⁹独立地代表氢原子,或者一起代表一个单一的碳-碳键;A代表一个可选择地取代的苯基。其中某些
异喹啉衍
生物是新颖的,还提供了制备这些化合物和含有它们的组合物的方法。
