Aminoketals, process for preparing them, a plant fungicide which comprises such an aminoketal and a process for producing such a fungicide, and the use of such an aminoketal for controlling phytopathogenic fungi

摘要

Aminoketals of the formula I IMAGE in which x and y each, independently of the other, denote O or -OCH2-, (R1)n denotes up to four substituents, with it also being possible for two neighbouring R1 substituents together to form a saturated or unsaturated ring, m is 0, 1, 2, 3 or 4, and R2 and R3 each, independently of the other, denote hydrogen, straight- chain or branched alkyl having up to 10 carbon atoms, unsubstituted or alkyl-substituted cycloalkyl, alkenyl, alkynyl or unsubstituted or alkyl-substituted arylalkyl, or R2 and R3, together with the nitrogen atom to which they are linked, form a saturated or unsaturated, substituted or unsubstituted heterocyclic ring which can optionally be aryl-fused or cycloalkyl-fused, and which can optionally contain one or more additional heteroatoms selected from O and N, and the preparation of these compounds, are described. The compounds I have a fungicidal, in particular plant fungicidal effect.
