  • Ruthenium catalyst for biarylic coupling; new steganolides
    Patent number: 4873349
    Abstract: A method for forming bridged biaryl compounds via the intramolecular oxidative biarylic coupling of precursor compounds containing two aromatic rings linked via a hydrocarbon chain is disclosed along with the ruthenium catalyst for its implementation and new compounds resulting therefrom. The biarylic coupling method is characterized in that the biarylic precursors are cyclized in the presence of the catalyst tetrakis(trifluoroacetate) of ruthenium (IV).
