Patent number: 6096920Abstract: Palladium-catalyzed arylation of an olefin (e.g., ethylene) with an aromatic halide (e.g., 2-bromo-6-methoxynaphthalene, m-bromobenzophenone, or 4-isobutyl-1-bromobenzene) is conducted in specified media. After a special acid or base phase separation procedure, palladium-catalyzed carbonylation of the olefinically-substituted aromatic intermediate is conducted in specified media using CO and water or an alcohol to form arylalkylcarboxylic acid or ester or substituted arylalkylcarboxylic acid or ester (e.g., racemic 2-(6-methoxy-2-naphthyl)propionic acid, 2-(3-benzoylphenyl)propionic acid, or 2-(4-isobutylphenyl)propionic acid). Catalyst recovery procedures enabling recycle of catalyst residues and efficient recovery of amine hydrogen halide scavenger and solvent used in the arylation reaction are described, as well as novel, highly efficient methods of conducting the carbonylation reaction.Type: GrantFiled: July 8, 1998Date of Patent: August 1, 2000Assignee: Albemarle CorporationInventors: Robert H.

Patent number: 6043279Abstract: Compounds, compositions, and methods for modulating processes mediated by Retinoid X Receptors using retinoid-like compounds which have activity selective for members of the subclass of Retinoid X Receptors (RXRs), in preference to members of the subclass of Retinoic Acid Receptors (RARs). Examples of such compounds are bicyclic benzyl, pyridinyl, thiophene, furanyl, and pyrrole derivatives. The disclosed methods employ compounds for modulating processes selectively mediated by Retinoid X Receptors.Type: GrantFiled: February 12, 1997Date of Patent: March 28, 2000Assignee: Ligand Pharmaceuticals, IncorporatedInventors: Marcus F. Boehm, Richard A. Heyman
