The invention relates to novel ferroportin inhibitors of the general formula (I) pharmaceutical compositions comprising them and the use thereof as medicaments, in particular for the prophylaxis and/or treatment of diseases caused by a lack of hepcidin or iron metabolism disorders, such as particularly iron overload states such as in particular thalassemia and hemochromatosis.

β-Enamino esters or amides can be synthesized in a single step by a carbonylative coupling of α-chloroimines with alcohols or amines under Pd-catalysis. The methodology has been also applied to the preparation of heteroaryl acetic acid derivatives starting from chloromethyl heteroaromatic rings containing a C-N double bond. The in situ generation of a β-imino acylpalladium species has been proposed as a key step for the process.

To obtain 2-benzimidazolyl acrylate 2, a new efficient synthesis of 2-benzimidazoleacetate, involving esterification of 2-benzimidazole acetic acid at low temperature as the crucial step, was developed. The generality and efficiency of the process was illustrated by the high-yield synthesis of methyl, ethyl, i-propyl, and n-butyl 2-benzimidazoleacetate. The Knoevenagel reaction of 2-benzimidazoleacetate with aromatic aldehydes was studied. It was found that only in the presence of a catalytic amount of morpholine could the Knoevenagel reaction proceed to give the expected 3-aryl-2-benzimidazolyl acrylate. A mechanism for the morpholinecatalyzed reaction is suggested. Springer Science+Business Media B.V. 2011.
