摘要

5-substituted thiol-4-(pyridinylcarbonyl)-cyclohexene-1,3-dione derivatives (I) and their salts, all isomers and tautomers are new. 5-substituted thiol- 4-(pyridinylcarbonyl)-cyclohexene-1,3-dione derivatives of formula (I) and their salts, all isomers and tautomers are new. R = 1-12C alkyl, 2-12C alkenyl or alkynyl, 3-12C allenyl, 3-12C cycloalkyl, 5-12C cycloalkenyl, R1-(1-12C alkylene or 2-12C alkenylene) (where alkylene and alkenylene may be interrupted by oxygen, S(O)p, or CO and substituted by one or more R2, or phenyl (optionally substituted 1-5 times by R11)), 3-12 membered aromatic or partially or fully saturated mono- or bi-cyclic ring system, (optionally containing 1-5 heteroatoms (nitrogen, oxygen and/or sulfur)) or 1-2 carbonyl (optionally substituted by one or more R3), with the ring system attached, via C or N atoms, directly or through a 1-6C alkylene or alkenylene linker (optionally interrupted by O or S(O)p and/or substituted by R4) to the S of S(O)nR, and substituents on N are other than halo, or halo, 1-12C alkylthio, cyano, C(X1)R6, C(X2)X3R7, C(X4)NR8R9, or, if n = 0, also hydrogen, cyano or isocyano or hydroxy, or NR80R90 when n = 1 or 2; Z1 = 1-3C alkyl; Y = hydrogen, chloro, bromo or 1-2C (halo)alkyl; n and p = 0-2; q = 0 or 1; and X1-X4 = oxygen or sulfur; The full definitions are given in the DEFINITIONS (Full Definitions) Field. An Independent claim is also included for the preparation of (I).
