摘要:在这里,我们描述了用于两个碳亲电体的直接还原偶联的光氧化还原辅助催化体系.最近的进展表明,镍催化剂对sp 3的偶联具有活性.-碳亲电试剂以及控制非常好,光驱动的耦合系统是可能的.我们的系统由镍催化剂,铱光敏剂和胺电子给体组成,能够以高收率偶联卤代烃.光谱学研究支持了一种机理,其中在可见光照射下,Ir光敏剂与三乙醇胺的结合能够还原镍催化剂,并使催化剂朝着碳亲电子试剂的交叉偶联的方向活化.此处开发的合成方法可在1 Mol%的催化剂和光敏剂低负荷下运行.催化体系也可以在没有反应添加剂(例如无机盐或碱)的情况下运行.一般有效的sp 2-sp 3 已经实现了对多种官能团均表现出耐受性的交叉偶联方案.

标题:Method for the synthesis of bis-tetrahydrofuranyl annonaceous acetogenins
发明人：HOYE THOMAS R; TAN LUSHI
权利人:UNIVERISTY OF MINNESOTA
摘要:A method for the synthesis of bis-tetrahydrofranyl Annonaceous acetogenins, including the natural products and analogs thereof, is provided which proceeds by the Pd-mediated coupling of a bis-tetrahydrofuranyl-subunit comprising a terminal alkyne, with a (C4)-hydroxybutenolide subunit comprising a terminal vinyl iodide, followed by selective reduction of the resulting enyne.

标 题:Synthesis of diols, for use as intermediates for polymeric materials, by starting from terminal diolefins
发明人：RICCI MARCO; GEMENTI FRANCESCO; PANELLA FRANCESCO; QUERCI CECILIA; UNGARELLI RAFFAELE
权利人:ENICHEM SPA
摘要:Disclosed is the synthesis of terminal diols, which are organic intermediates used in order to produce polymeric materials, by starting from terminal diolefins, which synthesis is based on the oxidation of diolefins to yield diepoxides, in a double-phase aqueous-organic system with hydrogen peroxide and in the presence of catalysts soluble in the organic phase, followed by a reaction of reduction of the resulting diepoxides.

标题:Method of regioselective synthesis of substituted benzoates
发明人：KRAUS GEORGE A
权利人:KRAUS GEORGE A; UNIV IOWA STATE RES FOUND INC
摘要:A method of synthesis of para-substituted benzoate esters and acids is provided, wherein the para-substituted regioisomer is obtained substantially free of the meta-substituted impurity, the method comprising contacting a coumalate ester or acid and an unactivated alkene at elevated temperature in the presence of a metal oxidation catalyst and an oxidant. The metal oxidation catalyst can be palladium, such as palladium on carbon, and the oxidant can be the oxygen gas in ambient air. The reaction can be carried out without solvent or in high boiling hydrocarbon solvents such as mesitylene. When the unactivated alkene is a monosubstituted alkene, yields of at least about 50 or 60% of para-substituted ester and acid products, respectively, are obtained, substantially free of the regioisomeric meta-substituted impurity.
