  • Second cycle asymmetric dihydroxylation reaction
    Publication number: 20020042545
    Abstract: A process for catalyzing asymmetric dihydroxylations of olefins employs an Os(VI) complex as a catalytic intermediate in the formation of chiral vicinal diol products. The process requires a chiral bidentate ligand that favors diol formation in the “second cycle” of asymmetric dihydroxylation.

  • Aminohydroxylation of Olefins
    Patent number: 6350905
    Abstract: Osmium-catalyzed aminohydroxylation reactions are accelerated and expanded in scope by the use of olefinic substrates having ionic groups, either anionic or cationic. The use of ionic groups on olefinic substrates also extends the aminohydroxylatable positions of unsaturations to include &agr;,&bgr;, &bgr;,&ggr;, and &ggr;,&dgr; positions, with respect to such ionic groups. A mechanism for the disclosed acceleration and extension is provided.
