Abstract:
A compound of formula (I) or an organic or inorganic salt thereof: ##STR9##wherein:R.sub.1, R.sub.2 and R.sub.3 are, independently of one another, chosen from H, OH and linear and branched C.sub.1 -C.sub.8 alkoxy radicals;R.sub.4 and R.sub.5 are, independently of one another, chosen from H and linear and branched C.sub.1 -C.sub.4 alkyl radicals; it being possible for R.sub.4 and R.sub.5, taken together, to form a 5- or a 6-membered ring;X.sub.1 and X.sub.2 are, independently of one another, chosen from--(CO)NR.sub.6 R.sub.7 groups in which R.sub.6 and R.sub.7 are, independently of one another, chosen from H and linear and branched C.sub.1 -C.sub.4 alkyl radicals; it being possible for R.sub.6 and R.sub.7, taken together, to form a 5- or a 6-membered ring, and--O(CO)R.sub.8 groups in which R.sub.8 is chosen from H and linear and branched C.sub.1 -C.sub.8 alkyl radicals;Z is chosen from compounds of formula (II) and formula (III) ##STR10##in which:R'.sub.1, R'.sub.2 and R'.sub.3 are, independently of one another, chosen from H, OH, and linear and branched C.sub.1 -C.sub.8 alkoxy radicals;X' is chosen from --(CO)NR'.sub.4 R'.sub.5 groups in which R'.sub.4 and R'.sub.5 are, independently of one another, chosen from H and linear and branched C.sub.1 -C.sub.4 alkyl radicals; it being possible for R'.sub.4 and R'.sub.5, taken together, to form a 5- or a 6-membered ring, and --O(CO)R'.sub.6 groups in which R'.sub.6 is chosen from H and linear and branched C.sub.1 -C.sub.8 alkyl radicals.
