| abstract |
The invention pertains to substituted cycloalkenes of general formula (I) and several methods of preparing them, as well as intermediate products and several methods for preparing them. In this formula (I), E stands for methylidene or nitrogen; G is a simple bond, oxygen, sulfur or alkandiyl or alkindiyl optionally substituted by halogen, hydroxy, alkyl, alkyl halide or cycloalkyl, or one of the following groups: -Q-CQ-, -CQ-Q-, -CH2-Q-, -Q-CH2-, -CQ-Q-CH2-, -CH2-Q-CQ-, -O-CQ-CH2-, -Q-CQ-Q-CH2-, -N=N-, -S(O)n-, -CH2-S(O)n-, -CQ-, -S(O)n-CH2-, -C(R1)=N-O-, -C(R1)=N-O-CH¿2?-, -N(R?2¿)-, -CQ-N(R2)-, -N(R2)-CQ-, -Q-CQ-N(R2)-, -N=C(R1)-Q-CH¿2?-, -N(R?2¿)-CQ-Q-, -CQ-N(R2)-CQ-Q-, -N(R2)-CQ-Q-CH¿2?-, -Q-C(R?1¿)=N-O-CH¿2?-, -N(R?2)-C(R1¿)=N-O-CH¿2?-, -O-CH2-C(R?1¿)=N-O-CH¿2?-, -N=N-C(R?1¿)=N-O-CH¿2?-, -T-Ar?1¿- or -T-Ar1-Q- wherein Ar1 is optionally substituted arylene, heteroarylene, cycloalkylene or heterocycloalkylene, Q is oxygen or sulfur; T is a simple bond, oxygen, sulfur, -CH¿2?-O-, CH2-S- or optionally substituted alkandiyl; m is 0, 1 or 2; R is alkyl, alkoxy, amino, hydroxylamino, alkoxyamino, alkylamino or dialkylamino; Y is methylene, oxygen, sulfur or an imino group ('azamethylene', NH, N- alkyl) optionally substituted by alkyl, and Z is optionally substituted alkyl, alkenyl, alkinyl, cycloalkyl, aryl or heterocyclyl. If E is oxygen, G is also alkendiyl optionally substituted by halogen, hydroxy, alkyl, alkyl halide or cycloalkyl, or -CH2-O-N=C(R?1¿)-. Compounds of formula (I) have a strong antimicrobial action and are used to combat undesirable microorganisms. The active ingredients are suitable for use as plant protectives, especially as fungicides. |
