  • Process and intermediates for the preparation of 4-aryl piperidines
    Patent number: 6998488
    Abstract: A novel process is provided for the preparation of 4-aryl piperidines, and the useful intermediates obtained therein. These compounds are intermediates for the synthesis of melanocortin-4 receptor (MC-4R), which are useful for the treatment of disorders such as obesity, diabetes, male sexual dysfunction, and female sexual dysfunction.
    Type: Grant
    Filed: March 8, 2004
    Date of Patent: February 14, 2006
    Assignee: Merck & Co., Inc.
    Inventors: Genevieve N. Boice, Karen M. Conrad, Edward G. Corley, Louis Matty, Jr., Jerry A. Murry, Cecile G. Savarin
  • Process for preparing cis- aminochromanols
    Patent number: 6384244
    Abstract: cis-aminochromanols are obtained in high yield and with high selectivity over their trans counterparts by hydrogenating the corresponding oximes in the presence of a catalyst and an acid selected from HBr, HCl, and organic sulfonic acid. The cis-aminochromanols can be employed as intermediates in the production of HIV protease inhibitors which are useful for treating HIV infection and AIDS.

  • Anionic grafts of monomers onto coal substrates
    Patent number: 4263123
    Abstract: Anionic grafting of olefinic monomers onto coal substrates is disclosed. The process comprises grafting polymeric side chains onto coal by contacting coal with a covalently bonded alkyl or aryl alkali metal initiator to generate carbon-alkali metal bonds and then reacting these bonds with an olefinically unsaturated monomer for a time sufficient to produce a grafted coal product having polymeric side chains bonded to the coal. The resulting coal grafts evidence enhanced solubility in organic solvents, and liquids derived from the coal grafts evidence reduced sulfur content.
