摘要:
The present invention relates to a method of reacting starting materials with an activating group, namely alkanes carrying a leaving group and/or olefins, with carbon dioxide under transition metal catalysis to give carboxyl group-containing products. It is a special feature of the method of the present invention that the carboxylation predominantly takes place at a preferred position of the molecule irrespective of the position of the activating group. The carboxylation position is either an aliphatic terminus of the molecule or it is a carbon atom adjacent to a carbon carrying an electron withdrawing group. The course of the reaction can be controlled by appropriately choosing the reaction conditions to yield the desired regioisomer.

摘要:
Rhein analogues that exhibit anti-proliferative activity, particular against cancer cells, are described herein. In some embodiments, the compounds contain a flat or planar ring system. Such rings system by facilitate non-covalent binding of the compounds to the DNA complex, such as by intercalation. In some embodiment, the compounds contain a flat or planar ring system as described above and one or more substituents which are alkylating moieties, electrophilic groups or Michael acceptors or groups which contain one or more alkylating moieties, electrophilic groups and/or Michael acceptors. The compounds described herein can also contain one more functional groups to improve the solubility of the compounds.
