标题:[ir(Ppy)2(Dtb-Bpy)]+ 的串联光氧化还原催化机制能够获得高能量的有机底物
摘要:我们报告了使用 [ir(Ppy)2(Dtb-Bpy)]+ (1+) 光催化剂减少能量需求底物的串联催化过程的发现.1+ 和三乙胺 (Tea) 之间光引发电子转移 (Pet) 的直接产物经过后续反应,反应生成以前未知的高度还原物质 (2).2 的形成通过辅助 Dtb-Bpy 配体的还原和半饱和发生,其中 Tea 自由基阳离子充当有效的氢原子供体,核磁共振,质谱和氘标记实验证实了这一点.稳态和时间分辨发光和吸收研究表明,在辐照后,2 与代表性受体(n-(二苯基亚甲基)-1-苯基甲胺;s)发生电子转移或质子耦合电子转移(pcet).这种新的光催化循环的周转伴随着 1+ 的重整而发生.我们通过提出机械途径的第一个例子来合理化我们的观察,其中两个不同但相互关联的光氧化还原循环提供了一个扩展的还原电位窗口,能够使用广泛的能量需求和合成相关的有机底物,包括芳基卤化物.

标 题:One-pot synthesis of squaramides
发明人：MÃ?RQUEZ LÓPEZ MARÃ?A EUGENIA; ALEGRE REQUENA JUAN VICENTE; PÉREZ HERRERA RAQUEL
权利人:UNIV ZARAGOZA; CONSEJO SUPERIOR INVESTIGACION
摘要:The present invention refers to the first one-pot synthesis of squaramides. The one-pot synthesis of squaramides described herein is an easy and straightforward procedure to obtain squaramide derivatives which saves energy, avoids time consuming purification steps, reduces costs and provides better yields as compared with those squaramides obtained through the traditional 'stop-and-go' approach. Moreover, the authors of the present invention herein demonstrate the efficiency of this one-pot process with the synthesis of three biologically active structures, improving in most of the cases the results of the previous stepwise syntheses.

摘要:(S)-(+)-3-(aminomethyl)-5-methyl-hexanoic acid or (S)-pregabalin is an anticonvulsive drug. In addition to its use as an anticonvulsive agent, pregabalin has also been indicated as a medicament in the treatment of anxiety, neuropathic pain and pain in patients with fibromyalgia. Provided herein are thioester intermediates in the synthesis of and processes for the synthesis of 3-(aminomethyl)-5-methyl-hexanoic acid in the (R) or (S) configuration.

标 题:Process for the solubilization of peptides and process for peptide synthesis
发明人：BERNARD JEAN-MARIE; BOUZID KAMEL; GERVAIS CHRISTIAN
权利人:RHONE POULENC CHIMIE
摘要:A process is disclosed for making peptides soluble in a water-immiscible organic solvent, comprising linking a lipophilic group with an amide or ester bond to the terminal carboxyl group of said peptide; when the lipophilic group is linked to L-serine, a molecule is obtained with a solubility in water at 25 DEG C. of less than 30 g/liter. This lipophilic group is non-polymeric and chemically defined. A process is also disclosed for the synthesis of peptides, optionally protected, in a liquid medium, wherein the starting material is an amino acid or peptide made soluble in an organic medium by a lipophilic group A-L linked to the carboxyl function of the starting amino acid or peptide, and are added to amino acids or peptides to be condensed which are activated on their acid function and protected on their amine function and are optionally protected on their side chain. The peptides resulting from the synthesis are used, where appropriate, for the synthesis of medicinal products, vaccines or agri-foodstuff or plant-protection.
