The invention relates to novel benzodioxole derivatives of the general formula I ##STR1## in which R.sub.1 represents an unsubstituted or substituted, aliphatic, aromatic or heteroaromatic radical, alk represents an alkylene, alkenylene or alkylidene radical having a maximum of 5 carbon atoms, n.sub.1 represents 0, 1 or 2 n.sub.2 represents 0 or 1, R.sub.2, R.sub.3 and R.sub.4 each represents, independently of the others, hydrogen, lower alkyl, lower alkoxy or halogen, and A represents the radical --O--R.sub.5, wherein R.sub.5 represents hydrogen or an unsubstituted or substituted, aliphatic or araliphatic hydrocarbon radical, or A represents the radical ##STR2## in which either R.sub.6 and R.sub.7 each represents, independently of the other, hydrogen or lower alkyl, or R.sub.6 and R.sub.7 are bonded to one another and, together with the adjacent nitrogen atom, represent optionally lower alkyl-substituted tetra- to hexa-methyleneimino, 4-morpholinyl or 1H-tetrazol-1-yl, such as, for example, 5-methyl-6-phenylsulphonyl-1,3-benzodioxole-2-carboxylic acid. The invention relates also to salts of compounds of the general formula I in which A represents OR.sub.5 wherein R.sub.5 represents hydrogen, with bases, and to acid addition salts of compounds of the general formula I in which the radical R.sub.1 has a basic character and to processes for the manufacture of the above compounds and the salts thereof and to pharmaceutical compositions containing them. These novel substances have diuretic and supplementary uricosuric action and may be used, preferably in the form of appropriate pharmaceutical compositions, for the treatment of oedema and hypertension.
