| abstract |
The present invention provides sulphonamides of the general formula: <IMAGE> (I) wherein R1 and R2, which can be the same or different, are hydrogen or halogen atoms or C1-C6-alkyl, trifluoro-methyl, cyano, carboxyl, alkoxycarbonyl, aminocarbonyl, N-alkylaminocarbonyl or N,N-dialkylaminocarbonyl radicals or, when R1 and R2 are alkyl radicals ortho to one another, R1 and R2 together with the carbon atoms to which they are attached, form a saturated or unsaturated C5-C7-alkylene ring, R3 is a hydrogen atom, an alkyl radical containing up to 6 carbon atoms, an acyl radical, a phenylalkyl or phenylalkenyl radical, the phenyl moiety of which can be substituted by halogen, alkyl or trifluoromethyl, C is a -(CH2)m-radical, in which m is 0, 1, 2 or 3, or a branched C2-C5-alkylene radical, whereby a methylene radical -CH2-of the group C can be replaced by an oxygen or sulphur atom or by a hydroxymethylene radical -CHOH-or carbonyl group -CO-, B is a 1,2-, 1,3-, 1,4-cyclohexylidene or 1,2- or 1,3-cyclopentylidene radical. |
