  • Chelating carbene ligand precursors and their use in the synthesis of metathesis catalysts
    Patent number: 7026495
    Abstract: Chelating ligand precursors for the preparation of olefin metathesis catalysts are disclosed. The resulting catalysts are air stable monomeric species capable of promoting various metathesis reactions efficiently, which can be recovered from the reaction mixture and reused. Internal olefin compounds, specifically beta-substituted styrenes, are used as ligand precursors. Compared to terminal olefin compounds such as unsubstituted styrenes, the beta-substituted styrenes are easier and less costly to prepare, and more stable since they are less prone to spontaneous polymerization. Methods of preparing chelating-carbene metathesis catalysts without the use of CuCl are disclosed. This eliminates the need for CuCl by replacing it with organic acids, mineral acids, mild oxidants or even water, resulting in high yields of Hoveyda-type metathesis catalysts.

  • Antioxidant and radical scavenging activity of synthetic analogs of desferrithiocin
    Publication number: 20040044220
    Abstract: Free radicals and reactive oxygen species have the potential to damage a wide variety of organic molecules, typically by oxidizing certain moieties. These damaging species can, for example, be produced by an organism as a by-product of cellular respiration or by the reaction of iron(II) and peroxide. The present invention includes methods of using aryl-substituted heterocyclic iron chelating compounds as antioxidants, as well as preventing the reduction of iron(III) to iron(II). In addition, the present invention provides methods of treating conditions such as inflammatory disease, neoplastic disease, and ischemic episodes.
