Abstract
Process for the preparation of aliphatic sulfur derivatives and their S-oxide analogs, containing carboxylic acid groups, whose compounds correspond to the formula, ** (See formula) ** wherein R and R 'are chosen from hydrogen atoms and linear or branched alkyl or alkenyl radicals, unsubstituted or substituted by one or more halogen atoms or one or more hydroxyl, carboxylic or sultonic acid groups, being a number between 0 and 2 inclusive, where n is an integer between 1 and 17 inclusive, the sum of the carbon atoms of the various hydrocarbon chains, including those of R and R ', being the maximum equal to 18 atoms of carbon, and its pharmaceutically acceptable salts being characterized in that a thiol of the formula R-SNa and a halogenated derivative of the formula X-R "-COO Na are condensed in a manner known per se, in alkaline medium, in the which R has the significance specified above, R "designates the group (See formula) of the above formula (I) and X is a halogen atom, to obtain, after acidification, the formula derivatives ** (See formula) ** then subjecting the compound of the aforementioned formula (II) thus obtained to a directed oxidation, to obtain the derivatives of the formula ** (See formula) ** and if desired, the compounds of formula (II) or - (III) are subjected to more boosted oxidation by preferably raising the temperature to about 80-90º C, to obtain the compounds of the formula: ** (See formula) ** in which R, R 'and n have the significance specified above, and if desired, the acid obtained in each case is reacted with a mineral or organic base to obtain the corresponding salt.
