Substituted pyrazolopyrimidines, methods for the production thereof, use of the same for controlling pathogenic fungi, and agents containing said compounds

摘要

The invention relates to substituted pyrazolopyrimidines of formula (I) wherein the substituents have the following designations: L represents halogen, alkyl, halogenalkyl, alkenyl, alkoxy, amino, NHR, NR₂, cyano, S(-O)_nA¹ or C(-O)A², R representing alkyl or alkylcarbonyl, A¹ representing hydrogen, hydroxy, alkyl, alkylamino or dialkylamino, n representing 0, 1 or 2, and A² representing alkenyl, alkoxy, halogenalkoxy or one of the groups cited for A¹; m represents 0 or 1 to 5; R¹ represents alkyl, halogenalkyl, cycloalkyl, halogencycloalkyl, alkenyl, alkadienyl, halogenalkenyl, cycloalkenyl, alkinyl, halogenalkinyl or cycloalkinyl, phenyl, naphthyl, or a five-membered to ten-membered saturated, partially unsaturated or aromatic heterocycle containing between one and four heteroatoms from the group O, N or S; and R² represents hydrogen or one of the groups cited for R¹. Together with the nitrogen atom to which they are bonded, R¹ and R² can form a five-membered to six-membered ring that can be interrupted by an atom from the groups O, N and S, and R¹ and/or R² can also be substituted according to the description. Furthermore, in formula (I): X represents halogen, cyano, OH, alkyl, alkoxy or halogenalkoxy; Y represents a five-membered to ten-membered saturated, partially unsaturated or aromatic heterocycle according to the description, or a group X or another group according to the description; p represents 1 or 2, the groups Y being potentially different when p=2; and p represents 0, when X is according to the description. The invention also relates to methods and intermediate products for producing said compounds, agents containing the same, and the use thereof for controlling phytopathogenic fungi.
