7-(1,3-Dioxocyclohex-2-ylcarbonyl)-1,4-oxathiin or -dithiin derivatives of formula (I) and their salts are new. L,M = H; 1-6C alkyl, 2-6C alkenyl, 2-6C alkynyl or alkoxy (all optionally substituted by 1-5 halogen or alkoxy); or halogen, CN or NO2; X = O, S, SO or SO2; n = 0-2; R1-R4 = H; 1-6C alkyl, 2-6C alkenyl, 2-6C alkynyl or alkoxy (all optionally substituted by 1-5 halogen or alkoxy); halogen; or phenyl (optionally substituted by one or more of alkyl, H, alkoxy, haloalkyl, haloalkoxy, halogen, NO2, CN and alkoxycarbonyl); or R2+R3 form a bond; Q = 1,3-dioxocyclohex-2-yl of formula (a); R5,R6,R8,R10 = H or alkyl; R7 = H; alkyl or 3-4C cycloalkyl (both optionally substituted by 1-3 of halogen, alkylthio and alkoxy); or alkoxy, 1-6C alkoxyalkyl or tetrahydropyran-3- or 4-yl; R9 = H, alkyl or COOR11; or R7+R9 complete a bond or a 3-6 membered carbocyclic ring; R11 = alkyl; unless specified otherwise alkyl moieties have 1-4C. Intermediates of formula (III) are also new. T = Cl, OH or alkoxy. |
