  • Patent number: 7211667
    Abstract: This invention provides a class of therapeutic compounds and methods for the treatment of mammals with physiological disorders, such as for example a frequently occurring type of essential hypertension, which are critically associated with the decreased binding of magnesium to the plasma membranes of their cells. These methods consist of administering to a mammal in need of such treatment a compound selected from a series of disubstituted trans, trans 1,3-butadienes, 1,3-disubstituted perhydrobutadienes, 1,2-disubstituted trans ethylenes and 1,2 disubstituted ethanes and disubstituted propanes, each of which embodies, in common, the unique structural feature essential for the biological activity of these compounds. This invention also provides for pharmaceutical formulations that employ these novel compounds.

  • Patent number: 7026478
    Abstract: A process for the production of compounds Ar—R1 by means of a cross-coupling reaction of an organometallic reagent R1-M with an aromatic or heteroaromatic substrate Ar—X catalyzed by one or several iron salts or iron complexes as catalysts or pre-catalysts, present homogeneously or heterogeneously in the reaction mixture. This new invention exhibits substantial advantages over established cross coupling methodology using palladium- or nickel complexes as the catalysts. Most notable aspects are the fact that (i) expensive and/or toxic nobel metal catalysts are replaced by cheap, stable, commercially available and toxicologically benign iron salts or iron complexes as the catalysts or pre-catalysts, (ii) commercially attractive aryl chlorides as well as various aryl sulfonates can be used as starting materials, (iii) the reaction can be performed under “ligand-free” conditons, and (iv) the reaction times are usually very short.
