    α-氨基酸和肽作为双功能试剂:通过回收 CO2 进行活化烯烃的羧化
    摘要:
    羧酸,包括氨基酸 (AA),已被广泛用作脱羧偶联的试剂。与之前释放 CO 2 的脱羧偶联相比作为废物副产品,我们在此报告了一种同时利用来自羧酸的烷基和羧基组分的新策略。在这种独特的策略下,羧酸在烯烃的氧化还原中性羧基化反应中充当双功能试剂。多样化、廉价且易于获得的 α-AA 通过可见光光氧化还原催化参与活化烯烃的这种双官能化,提供各种有价值但难以获得的 γ-氨基丁酸衍生物 (GABA)。此外,一系列二肽和三肽也参与了这种光催化羧化。尽管由于 CO 2的低浓度和定量量,该系统存在一些挑战,以及非生产性副反应,如羧酸的加氢脱羧和烯烃的加氢烷基化,实现了优异的区域选择性和中到高的化学选择性。该工艺具有催化剂负载量低、反应条件温和、步骤和原子经济性高、官能团耐受性好等特点,并且易于扩展。所得产品经过高效衍生,整个过程适合应用于复杂化合物的后期改性。机理研究表明,碳负离子是催化生成的,它是与CO 2反应的关键中间体,CO

  • Préparation des organozinciques dérivés de l'α-bromométhyl acrylate d'éthyle et de ses homologues
    作者:Najat El Alami、Chantal Belaud、Jean Villiéras

    日期:1988.6
    α-bromoalkyl acrylates (aliphatic and alicyclic) results in high yields when carried out on 30 mesh activated granular zinc, between 14 and 20°C in ethereal solvents (THF, DME, ether). Under these conditions duplication can be minimized (5–15%) especially with t-butyl acrylates. These α-functional allylic organozinc derivatives have been characterized by hydrolysis and coupling with benzaldehyde.
    各种α-溴烷基丙烯酸酯(脂族和脂环族)的溴锌衍生物的制备,在醚化溶剂(THF,DME,乙醚)中,在14至20°C的30目活化的粒状锌上进行时,可产生高收率。在这些条件下,尤其是使用丙烯酸叔丁酯时,重复现象可以降到最低(5-15%)。这些α-官能烯丙基有机锌衍生物的特征在于水解并与苯甲醛偶联。

  • POROUS MATERIAL HAVING HIERARCHICAL POROUS STRUCTURE AND PREPARATION METHOD THEREOF

    Disclosed are porous ceramic balls with a hierarchical porous structure ranging in size from nanometers to micrometers, and preparation methods thereof. Self-assembly polymers and sol-gel reactions are used to prepare porous ceramic balls in which pores ranging in size from ones of nanometers to tens of micrometers are hierarchically interconnected to one another. This hierarchical porous structure ensures high specific surface areas and porosities for the porous ceramic balls. Further, the size and distribution of the pores can be simply controlled with hydrophobic solvent and reaction time. The pore formation through polymer self-assembly and sol-gel reactions can be applied to ceramic and transition metals. Porous structures based on bioceramic materials, such as bioactive glass, allow the formation of apatite therein and thus can be used as biomaterials of bioengineering, including bone fillers, bone reconstruction materials, bone scaffolds, etc.
