Abstract
The present invention provides sulphonamides of the general formula: ##STR1## wherein R.sup.1 and R.sup.2, which can be the same or different, are hydrogen or halogen atoms or C.sub.1 -C.sub.6 -alkyl, trifluoro-methyl, cyano, carboxyl, alkoxycarbonyl, aminocarbonyl, N-alkylaminocarbonyl or N,N-dialkylaminocarbonyl radicals or, when R.sup.1 and R.sup.2 are alkyl radicals ortho to one another, R.sup.1 and R.sup.2 together with the carbon atoms to which they are attached, form a saturated or unsaturated C.sub.5-C.sub.7 -alkylene ring, R.sup.3 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 --(CH.sub.2).sub.m --radical, in which m is 0, 1, 2 or 3, or a branched C.sub.2 -C.sub.5 -alkylene radical, whereby a methylene radical --CH.sub.2 --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.
