New imidazolopyrimidine derivatives useful for controlling unwanted microorganisms, e.g. phytopathogenic fungi

摘要

Imidazolopyrimidine derivatives (I) are new. Imidazolopyrimidine derivatives of formula (I) and their salts are new. R1>H, R2> or optionally substituted alkyl, alkenyl, alkynyl, cycloalkyl or heterocyclyl; R2>an optionally halogenated organic group with 3-13 C atoms and one or more Si atoms and optionally 1-3 heteroatoms (O, N, S); NR1>R2>an optionally substituted heterocyclic ring that contains one or more Si atoms and/or is substituted with R2>; R3>halo or an optionally substituted aryl, heterocyclyl, alkyl, alkenyl, alkynyl, cycloalkyl, aralkyl, amino, 1-8C alkoxy, 1-8C alkylthio, 6-10C aryloxy, 6-10C arylthio, heterocyclyloxy, (6-10C)aryl(1-4C)alkoxy, (6-10C)aryl(1-4C)alkylthio, heterocyclyl(1-4C)alkoxy or heterocyclyl(1-4C)alkylthio group; R4>, R5>H or optionally halogenated alkyl or cycloalkyl; X : halo, CN or optionally substituted alkyl, alkoxy or phenyl. Independent claims are also included for: (1) a process for preparing (I); and (2) controlling unwanted microorganisms by applying (I) onto the microorganisms and/or their environment. [Image] ACTIVITY : Plant antifungal; Plant antibacterial; Antialgal; Fungicide; Antibacterial. In a protective test against Podosphaera leucotricha on young apple trees, one or more compounds (unspecified) had an activity of more than 90% at an application rate of 100 g/ha. MECHANISM OF ACTION : None given.
