Abstract:
An isoxazolopyrimidinone of formula (I) in whichR1 represents (C3-C8)-cycloalkyl or represents straight-chain or branched alkyl having up to 4 carbon atoms, A represents radicals of the formulae â€ƒin which R2 and R7 are identical or different and represent hydrogen or straight-chain or branched alkyl having up to 4 carbon atoms, R3, R4, R5 and R6 are identical or different and represent hydrogen, a 5- to 6-membered aromatic heterocycle selected from the group consisting of pyridyl, pyrimidyl, pyridazinyl, thienyl, furyl, pyrrolyl, thiazolyl, oxazolyl or imidazolyl, or aryl having 6 to 10 carbon atoms, where the ring systems are optionally substituted, up to three times, identically or differently, by hydroxyl, halogen, (C1-C5)-alkyl or (C1-C6)-alkoxy, or R3, R4, R5 and R6 are identical or different and represent (C1-C6)-alkyl which is optionally substituted by aryl having from 6 to 10 carbon atoms and can, for its part, be substituted, up to 3 times, identically or differently, by (C1-C6)-alkyl, (C1-C6)-alkoxy, hydroxyl or halogen, or R3 and R4 and/or R5 and R6, together with the nitrogen atom to which they are bonded, form radicals of the formulae â€ƒwhere R8 represents hydrogen or (C1-C6)-alkyl which is optionally substituted by hydroxyl, and R9 represents hydrogen or hydroxyl, and the salts, N-oxides and isomeric forms thereof.
