标题:黄曲霉紧密相关的baeyer-Villiger单加氧酶之间的功能差异
摘要:Baeyer-Villiger单加氧酶(bvmo)催化将酮化学,区域和对映选择性氧化为酯和内酯.迄今为止,尽管已经经常证明使用真菌进行的拜耳-维利格氧化作用,但是大多数可用的克隆bvmos都来自细菌.在这里,我们报告从真菌黄曲霉的四个bvmos的克隆和表征nrrl3357.系统发育分析表明,这四个bvmo与其他特征明确的bvmo包括一个明显的组聚在一起,包括环己酮,苯丙酮和4-羟基苯乙酮单加氧酶.在bvmo的grogan分类/聚类的基础上,我们将bvmo的这一新组指定为vi组.Vi组bvmo显示出与环戊酮单加氧酶(cpmo)型bvmo(i组)的早期差异.使用环状,双环,脂肪族和芳基酮进行的底物分析显示,不仅在这组新的bvmo与cpmo型bvmo之间,而且在四个黄曲霉之间,在功能和特异性上也存在明显的差异.Bvmo旁系同源物,尽管它们具有很高的序列相似性.这项研究不仅有助于增加可用bvm

摘要:A process for the synthesis of novel compounds is described comprising reacting tetrachloroethylene with substances containing active methylene group in the presence of free radical initiators. Also, a process for grafting tetrachloroethylene is described comprising reacting these compounds with polymers containing active methylene group in the presence of free radical initiators. Furthermore, a method of conducting such reactions to high conversion is described, comprising conducting the reactions in the reflux condensate. The present invention provides a novel and high yield route for heretofore unobtainable materials.

标 题:Synthesis of olefinic alcohols via enzymatic terminal hydroxylation
发明人：COELHO PEDRO; CHEN MIKE M Y; MEINHOLD PETER; CHO CATHERINE MEE-HIE; BUI VU; HEEL THOMAS

摘要:In certain aspects, the present invention provides methods for producing terminally hydroxylated alkenes and alkynes by contacting an unsaturated or saturated hydrocarbon substrate with a hydroxylase enzyme. Exemplary terminal hydroxylases useful for carrying out the methods of the invention exhibit strong selectivity towards one terminal carbon of a hydrocarbon substrate and include, but are not limited to, non-heme diiron alkane monooxygenases, cytochromes P450 (e.g., cytochromes P450 of the CYP52 and CYP153 family), as well as long chain alkane hydroxylases. In some embodiments, the terminally hydroxylated alkene or alkyne is further converted to a terminal alkenal. In certain embodiments, terminally hydroxylated alkenes and alkynes are useful as insect pheromones which modify insect behavior. In other embodiments, terminally hydroxylated alkenes and alkynes are useful intermediates for producing pheromones via acetylation or oxidation of the alcohol moiety.

标题:Synthesis of straight-chain lepidopteran pheromones through one- or two-carbon homologation of fatty alkenes
发明人：WAMPLER KEITH M; LEE CHOON WOO; ROZZELL DAVID
权利人:PROVIVI INC
摘要:Methods for the preparation of alkenes including insect pheromones are described. The methods include homologation reactions employing reagents such as 1,3-diesters, epoxides, cyanoacetates, and cyanide salts for elongation of starting materials and intermediates by one or two carbon atoms. The alkenes include insect pheromones useful in a number of agricultural applications.

标 题 :Latex compositions containing ethylenically unsaturated esters of fatty compounds and applications thereof
发明人：THAMES SHELBY FRELAND; PANJNANI KAMLESH GOPICHAND; FRUCHEY OLAN STANLEY
权利人:UNIV SOUTHERN MISSISSIPPI
摘要:Novel latex or emulsion compositions containing internally plasticizing and crosslinkable monomers derived from traditional semi-drying or non-drying oils are disclosed and claimed. The monomers are ethylenically unsaturated derivatives of long-chain olefinic compounds. Preferred embodiments include latex formed from acrylate or methacrylate esters of fatty alcohols. A process for the synthesis of the latex composition is also disclosed, which involves (a) polymerization of the ethylenically unsaturated derivatives of a long-chain olefinic compound in an aqueous phase with at least one other copolymerizable monomer; and (b) blending of so formed polymer with at least one drier and a surfactant to form the novel latex or emulsion compositions. These compositions form films at low minimum film forming temperatures (MFT) ranging from -5 to 10° C. and cure to above ambient glass transition (Tg) polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions. These compositions are therefore useful in waterborne coatings, contact and pressure sensitive adhesives, and inks.

摘要:Methods for preparation of olefins, including 8- and 11-unsaturated monoenes and polyenes, via transition metathesis-based synthetic routes are described. Metathesis reactions in the methods are catalyzed by transition metal catalysts including tungsten-, molybdenum-, and ruthenium-based catalysts. The olefins include insect pheromones useful in a number of agricultural applications.

摘要:Novel latex or emulsion compositions containing internally plasticizing and crosslinkable long-chain alkenol ester monomers are disclosed and claimed. Preferred embodiments include latex formed from acrylate or methacrylate esters of long-chain alkenols. A process for the synthesis of the latex composition is also disclosed, which involves (a) esterification of a long-chain alkenol with an ethylenically unsaturated carboxylic acid; (b) polymerization of the ethylenically unsaturated ester in an aqueous phase with at least one other copolymerizable monomer; and (b) blending of so formed polymer with at least one drier and a surfactant to form the novel latex or emulsion compositions. These compositions form films at low minimum film forming temperatures (MFT) ranging from −5 to 10° C. and cure to above ambient glass transition (T g ) polymers without the use of traditional organic cosolvents which contribute to environmental pollution via volatile organic compounds (VOCs) emissions. These compositions are therefore useful in waterborne coatings, contact and pressure sensitive adhesives, and inks.
