N-BISARYL- AND N-ARYL-CYCLOALKYLIDENYL-ALPHA-HYDROXY- AND ALPHA-ALKOXY ACID AMIDES

摘要

The invention relates to N-bisaryl- and N-aryl-cycloalkylidenyl-a-hydroxy- a nd a-alkoxy acetic acid amides of the general formula (I) including the optical isomers thereof and mixtures of such isomers, wherein R1 is hydrogen, C1- C12alkyl; C2-C12alkenyl; C2-C12alkynyl; C1-C12haloalkyl; R2 is hydrogen; optionally substituted alkyl; optionally substituted alkenyl or optionally substituted alkynyl; R3 is optionally substituted aryl or optionally substituted heteroaryl; A is an optionally substituted saturated or unsaturated C3-C8-cycloalkylidene, optionally substituted phenylidene or optionally substituted saturated or unsaturated heterocyclylidene bridge, R4 and R5 are each independently hydrogen or an organic radical, and R6 is hydrogen; tri-C1-C4alkyl-silyl; di-C1-C4alkyl-phenylsilyl; C1-C4alkyl- diphenylsilyl; triphenylsilyl; optionally substituted alkyl; optionally substituted alkenyl or optionally substituted alkynyl. The compounds possess plant-protecting properties and are suitable for protecting plants against infestation by phytopathogenic miroorganism, especially fungi.
