| 摘要 |
The invention relates to ±-oxygenated or ±-thiolated carboxylic acid phenethylamide derivatives of the general formula I
including the optical isomers thereof and mixtures of such isomers, wherein A stands for optionally substituted aryl or optionally substituted heteroaryl; X is oxygen or sulfur; Y is oxygen or sulfur; R 1 is hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, haloalkyl, haloalkenyl, haloalkynyl or halocycloalkyl; R 2 is hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkyl-alkyl, alkoxy-alkyl, alkoxy-alkenyl, alkoxy-alkynyl, whereof all alkyl- alkenyl-, alkynyl-, or cycloalkyl-groups me be optionally substituted by halogen; or optionally substituted aryl-alkyl, optionally substituted aryl-alkenyl, optionally substituted aryl-alkynyl or optionally substituted aryloxy-alkyl; R 3 is hydrogen, alkyl, alkenyl, alkynyl, cycloalkyl, cycloalkyl-alkyl, alkoxy-alkyl, alkoxy-alkenyl, alkoxy-alkynyl, whereof all alkyl- alkenyl-, alkynyl-, or cycloalkyl-groups me be optionally substituted by halogen; or is optionally substituted aryl-alkyl, optionally substituted aryl-alkenyl, optionally substituted aryl-alkynyl, optionally substituted aryloxy-alkyl, optionally substituted heteroaryl-alkyl, optionally substituted heteroaryl-alkenyl or optionally substituted heteroaryl-alkynyl; R 4 is alkyl, alkenyl, alkynyl, alkoxy-alkyl, alkoxy, alkenyloxy, alkynyloxy, alkylthio, alkanoyl, alkylamino, dialkylamino, alkoxycarbonyl, whereof all alkyl- alkenyl or alkynyl-groups me be optionally substituted by halogen; or is halogen, cyano, nitro, amino, formyl or carboxyl; R 5 is hydrogen, alkyl, alkenyl or alkynyl; n is an integer 0,1, 2, 3, or 4; B 1 represents a bridge member -(CR 10 R 11 ) q - or -(CHR 10 R 11 ) r -Z-(CR 12 R 13 ) s , wherein q is an integer 2, 3 or 4; r is an integer 0, 1, 2, 3; s is an integer 1, 2 or 3, provided that (r + s) is either 1, 2 or 3; Z is -O-, -S-, -SO- -SO 2 -, NR 6 -, -CO-, -OOC-, -COO-, -NR 6 -CO- or -CO-NR 6 - ; R 6 is hydrogen or alkyl ; R 10 , R 11 , R 12 and R 13 independently of each other are hydrogen or alkyl ; and B 2 is an alkylene bridge. These compounds possess useful plant protecting properties and may advantageously be employed in agricultural practice for controlling or preventing the infestation of plants by phytopathogenic microorganisms, especially fungi. |
