Claim:
A compound of general formula: in which: R and R′ independently represent a linear or branched C 1 -C 7 alkyl radical or an aryl group which is unsubstituted or substituted by one or more radicals chosen from halogens, linear or branched C 1 -C 3 alkyl radicals and —OH radicals; R″ is hydrogen or a CO—R 1 group in which R 1 is a linear or branched C 1 -C 7 alkyl radical or an aryl group which is unsubstituted or substituted by one or more radicals chosen from halogens, linear or branched C 1 -C 3 alkyl radicals and —OH radicals; and the dimers formed by a disulfide bridge from one and/or other of the two sulfur atoms of the compounds of general formula I composed of the R″ radicals or of the R′ CO— radicals of the two molecules, and the corresponding thiazolidine forms.
