标题:Solid phase and combinatorial synthesis of compounds on a solid support
发明人：ELLMAN JONATHAN A
权利人:UNIV CALIFORNIA
摘要:Methods, compositions, and devices for synthesizing combinatorial libraries of various useful compounds, such as benzodiazepines, prostaglandins, β-turn mimetics and glycerol-derived drugs is described. In order to expediently synthesize such combinatorial libraries of derivatives based upon these core structures, a general methodology for the solid phase synthesis of these derivatives is also provided. This disclosure thus also describes an important extension of solid phase synthesis methods to nonpolymeric organic compounds.

标 题:Solid-phase synthesis of codeine from morphine
发明人：CORCORAN ROBERT C; MA JUNNING
权利人:UNIV COMMUNITY COLLEGE SYS NEV
摘要:The specification describes a methylation resin comprising methyl(dialkyl)anilinium salts or methyl(diaryl)anilinium salts covalently bonded to the resin. The methylation resin is used in the solid-phase synthesis of codeine from morphine. Accordingly, the specification describes a process for methylating morphine to form codeine by loading morphine onto a methylation resin comprising methyl(dialkyl)anilinium salts or methyl(diaryl)anilinium salts covalently bonded to the resin; contacting the loaded resin with sufficient hydrocarbon or ether solvent to cover the loaded resin; and heating the loaded resin in the hydrocarbon or ether solvent under sufficient conditions to form codeine. The methylating resin may be used to methylate phenolic moieties on other compounds and to esterify compounds containing carboxylic acid moieties.

标题 :Catalyst for synthesis of carbon single-walled nanotubes
发明人：HARUTYUNYAN AVETIK; TOKUNE TOSHIO; FERNANDEZ ELENA MORA
权利人:HONDA MOTOR CO LTD; UNIV OHIO STATE RES FOUND
摘要:Methods and processes for preparing supported metal catalysts are provided, where the supported metal catalysts can be used for the bulk synthesis of carbon nanotubes. The salts of the metal and the support are selected such that they are soluble in the same solvent. The catalyst can be prepared from the liquid phase through joint precipitation of the metal and the support material. The methods can be used to increase the metal load on the support. Use of the catalysts increases the yield of the carbon nanotubes.
