专利号:US-7314960-B1 优先权日:2006-09-28 标 题:Catalytic synthesis of oxygenate from alcohol 发明人:LIN SHENG-DIANN; HSIAO TING-CHOU 权利人:UNIV YUAN ZE 摘要:The present invention discloses a method for catalytic synthesis of oxygenate from alcohol. At first, a feeding material comprising at least one alcohol is provided. Next, a copper-containing catalyst is provided and the catalyst further comprises at least one metal element selected from the group consisting of the following: zinc, magnesium, and aluminum elements. Following that, a catalytic reaction of the feeding material over the copper-containing catalyst is carried out to synthesize at least one oxygenate.

A process for producing pyrroles such as 2,5-dimethylpyrrole, and structurally similar pyrrole compounds, is also disclosed.
专利号:US-7737287-B2 优先权日:2002-03-28 标 题 :Anomeric derivatives of monosaccharides 发明人:MEUTERMANS WIM; WEST MICHAEL LEO; GIANG THANH LE; ADAMSON GEORGE; SCHAFER KARL; ABBENANTE GIOVANNI 权利人:ALCHEMIA LTD 摘要:This invention relates to combinatorial libraries of potentially biologically active mainly monosaccharide compounds and to methods of preparing same. These compounds are variously functionalized, with a view to varying lipid solubility, size, function and other properties, with the particular aim of discovering a drug or drug-like compound, or compounds with useful properties. The invention provides intermediates, processes and synthetic strategies for the solution or solid phase synthesis of monosaccharides, variously functionalized about the sugar ring, including the addition of aromaticity and charge, and the placement of amino acid and peptide side chain units of isosteres thereof.
专利号:US-7314962-B2 优先权日:2005-04-15 标题:Alkylation of aromatic compounds 发明人:HARMER MARK ANDREW; JUNK CHRISTOPHER P; MANZER LEO ERNEST 权利人:DU PONT 摘要:The present invention relates to the synthesis of alkylated aromatic compounds using ionic liquids as the solvent. Alkylated aromatic compounds are synthesized by reacting an aromatic compound with a monoolefin in the presence of an acid catalyst.
专利号:US-8138272-B2 优先权日:2006-05-22 标 题:Preparation of polymer conjugates of therapeutic, agricultural, and food additive compounds 发明人:KONRADI ANDREI W; SMITH JENIFER L 权利人:KONRADI ANDREI W; SMITH JENIFER L; ELAN PHARM INC 摘要:This invention provides an improved synthesis of polymer conjugates of formula (I), n nof agricultural, therapeutic, and food additive compounds. In particular, a process is described for the preparation of conjugates by treating primary or secondary alcohol substituents of active compounds with polymeric nucleophiles using “Mitsunobuâ€? or related reaction conditions.
