(57) [Summary]nThe present invention provides compounds of the general formulanEmbedded imagen And their possible isomers and mixtures of their isomers. Where n is 0 or 1 and R 1 Is unsubstituted or C 1 ~ C Four Alkoxy, C 1 ~ C Four Alkylthio, C 1 ~ C Four Alkylsulfonyl, C Three ~ C 8 Cycloalkyl, cyano, C 1 ~ C 6 Alkoxycarbonyl, C Three ~ C 6 Alkenyloxycarbonyl or C Three ~ C 6 C optionally substituted by alkynyloxycarbonyl 1 ~ C 12 Alkyl; C Three ~ C 8 Cycloalkyl; C Two ~ C 12 Alkenyl; C Two ~ C 12 Alkynyl; C 1 ~ C 12 Haloalkyl; or the group NR 11 R 12 (R 11 And R 12 Is each independently of the other hydrogen or C 1 ~ C 6 Alkyl, or together, tetramethylene or pentamethylene); Two And R Three Is hydrogen, each independently of the other; 1 ~ C 8 Alkyl; hydroxy, C 1 ~ C Four Alkoxy, mercapto, or C 1 ~ C Four C substituted by alkylthio 1 ~ C 8 Alkyl; C Three ~ C 8 Alkenyl; C Three ~ C 8 Alkynyl; C Three ~ C 8 Cycloalkyl; C Three ~ C 8 Cycloalkyl-C 1 ~ C Four Alkyl or two groups R Two And R Three Together with the carbon atom to which they are attached form a 3- to 8-membered ring; Four , R Five , R 6 , And R 7 Are the same or different and are each independently of the other hydrogen or C 1 ~ C Four Alkyl, R 8 Is C 1 ~ C 6 Alkyl, C Three ~ C 6 Alkenyl, or C Three ~ C 6 Alkynyl, wherein A is C 1 ~ C 6 Alkylene and B is optionally monocyclic or polycyclic unsubstituted or substituted aryl, optionally monocyclic or polycyclic unsubstituted or substituted heteroaryl, C Four ~ C 12 Alkyl or C Three ~ C 8 Cycloalkyl. The novel compounds have plant protection properties and are suitable for protecting plants from infestation by phytopathogenic microorganisms. |
