专利号:US-5110961-A 优先权日:1989-12-21 标 题:Catalytic process for the synthesis of an alcohol, new metal complexes and process for the synthesis of these complexes 发明人:LECOLIER SERGE; MORTREUX ANDRE; PETIT FRANCIS; SAMAIN HENRI 权利人:POUDRES & EXPLOSIFS STE NALE 摘要:The invention relates to a catalytic process for the synthesis of an alcohol by reaction of an epoxide with a nucleophilic compound containing a labile hydrogen, such as an alcohol, a phenol, a primary amine or a carboxylic acid. n The catalyst is a metal complex of general formula (I) n [M[Co(CO) 4 ] 2 ] x in which x is equal to 1 or 2 and M denotes tin, lead and cadmium. n The reaction preferably takes place in the presence of carbon monoxide. n This process makes it possible to increase the yield and the selectivity of the reaction and the stereoselectivity for alcohol in the case of which the hydroxyl formed is attached to the least hindered carbon atom of the epoxide. n The invention also relates to the new complexes of formula (I) in which x equals 2. n It also relates to a process for the electrosynthesis of these new compounds by electroreduction of Co 2 (CO) 8 in an organic solvent medium in a cell in which the anode consists of the metal M, followed by isolation of the complex, the temperature of the reaction mixture and that at which the complex is isolated being lower than 25° C.

专利号:US-6919382-B2 优先权日:2000-08-31 标 题 :Preparation and uses of conjugated solid supports for boronic acids 发明人:HALL DENNIS G 权利人:UNIV ALBERTA 摘要:The invention provides novel solid supports comprising dihydroxyalkyl aminoalkyl and dihydroxyalkylaminobenzyl groups, and methods for making and using them. The supports are particularly useful for immobilizing and derivatizing functionalized boronic acids for use in solid phase synthesis, such as those used in combinatorial chemistries. The compositions and methods of the invention are also useful as scavenger solid supports, e.g., in solution-phase parallel synthesis of small molecule libraries, and for use in resin-to-resin transfer reactions via phase transfer of solid supported boronic acids under both aqueous and anhydrous conditions. The methods of the invention provide convergent solid-phase synthesis of symmetrically or unsymmetrically functionalized compounds, such as biphenyl compounds. Also provided are synthesizer devices, e.g., semiautomated parallel synthesizers.
专利号:WO-0009528-A1 优先权日:1998-08-13 标题:Lower alkyl ester recycling synthesis 发明人:KENNEALLY COREY JAMES; TROUT JAMES EARL; SARAMA ROBERT JOSEPH; HOWIE JOHN KEENEY 权利人:PROCTER & GAMBLE; KENNEALLY COREY JAMES; TROUT JAMES EARL; SARAMA ROBERT JOSEPH; HOWIE JOHN KEENEY 摘要:Process for synthesizing and purifying polyol fatty acids polyesters or other nondigestible fats selected from the group of esterified linked alkoxylated polyols and esterified epoxide extended polyols, in which unreacted lower alkyl ester is recovered from a reaction mixture and recycled for use in the synthesis of the nondigestible fat. The process includes the steps of reacting an excess of lower alkyl ester with polyol to esterify hydroxyl groups thereof and form polyol fatty acid polyester, separating at least a portion of the unreacted lower alkyl ester from the polyol fatty acid polyester, and recycling the separated unreacted lower alkyl ester for further reaction with polyol or partially esterified polyol. The recycled lower alkyl ester is substantially free of lower alkyl ester degradation reaction products, such as carbonyls and free fatty acids.
