  • 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.

  • Patent number: 6348615
    Abstract: A process for producing (2R, 3S)-3-amino-4-phenylbutane-1,2-epoxide compounds which comprises treating a (2S, 3S)-3-amino-1-halo-2-hydroxy-4-phenylbutane compound or a (2S, 3S)-3-amino-4-phenylbutane-1,2-epoxide with a carboxylic acid quaternary ammonium salt or a carboxylic acid metal salt a quaternary ammonium salt and a quaternary ammonium salt, to give a (2S, 3S)-1-acyloxy-3-amino-2-hydroxy-4-phenylbutane compound, further treating the same with a sulfonic acid halide in the presence of an organic base to give a (2S, 3S)-1-acyloxy-3-amino-2-sulfonyloxy-4-phenylbutane compound, furthermore treating said compound with an inorganic base. An intermediate for the production of an HIV protease inhibitor can be produced from L-phenylalanine.

  • Patent number: 6337350
    Abstract: Derivatives of aryl and heterocyclic ureido and aryl and heterocyclic carboxamido phenoxy isobutyric acids have been found to inhibit the nonenzymatic glycation of proteins which often results in formation of advanced glycation endproducts and crosslinks. Many other phenoxyisobutyric acid derivatives as well as certain other compounds as set out in this disclosure also have been found to inhibit the nonenzymatic glycation of proteins. The nonenzymatic glycation and crosslinking of proteins is a part of the aging process with the glycation endproducts and crosslinking of long-lived proteins increasing with age. This process is increased at elevated concentrations of reducing sugars in the blood and in the intracellular environment such as occurs with diabetes. The structural and functional integrity of the affected molecules become perturbed by these modifications and can result in severe consequences.
