• The Selective<i>N</i>-Monoalkylation of Amides with Alkyl Halides in the Presence of Alumina and KOH
  作者：Kazuaki Sukata

  DOI：10.1246/bcsj.58.838

  日期：1985.3

  The effects of alumina impregnated with KOH (KOH/Al2O3) and a mixture of alumina and powdered KOH (KOH+Al2O3) have been examined using the alkylation of benzamide under various conditions. In each case, alkylation occurs exclusively in the pores of the alumina, the extent depending upon the alumina-pore size. For both yield and selectivity for N-monoalkylation, KOH+Al2O3 is superior to KOH/Al2O3. Dioxane is the best of the solvents employed. It is proposed that, in dioxane, an enolate-like species, (Remark: Graphics omitted.), exists as stable ion-pair aggregates, which are the true reactants in the pore. This method, using KOH/Al2O3 or KOH+Al2O3, has been applied to N-alkylation of the other amides, giving the N-monoalkylated products in substantial yields with extremely high selectivities. 2-Phenylacetamide is regioselectively N-monoalkylated in high yields. This regioselectivity is explained in terms of steric hindrance.

  使用KOH浸渍的氧化铝（KOH/Al2O3）和氧化铝与粉末状KOH的混合物（KOH+Al2O3），在不同条件下研究了苯甲酰胺的烷基化反应。在每种情况下，烷基化反应仅在氧化铝的孔隙中发生，其程度取决于氧化铝的孔径大小。对于N-单烷基化的产率和选择性，KOH+Al2O3优于KOH/Al2O3。二氧六环是所使用溶剂中最好的。研究表明，在二氧六环中，类似于烯醇盐的物种（注：图形省略）以稳定的离子对聚集形式存在，这些是孔隙中的真正反应物。这种方法使用KOH/Al2O3或KOH+Al2O3，已应用于其他酰胺的N-烷基化，以极高的选择性获得了大量的N-单烷基化产物。2-苯基乙酰胺以高产率选择性地进行N-单烷基化。这种区域选择性可通过空间位阻来解释。

  Transamidation reactions are often mediated by reactive substrates in the presence of overstoichiometric activating reagents and/or transition metal catalysts. Here we report the use of CO2 as a traceless catalyst: in the presence of catalytic amounts of CO2, transamidation reactions were accelerated with primary, secondary, and tertiary amide donors. Various amine nucleophiles including amino acid

  在过量化学计量的活化试剂和/或过渡金属催化剂的存在下，转酰胺基反应通常由反应性底物介导。在这里，我们报告了使用 CO 2作为无痕催化剂：在催化量的 CO 2存在下，使用伯、仲和叔酰胺供体加速转酰胺反应。包括氨基酸衍生物在内的各种胺类亲核试剂都被耐受，这表明转酰胺基在肽修饰和聚合物降解中的实用性（例如，Nylon-6,6）。特别是，N , O -二甲基羟基酰胺（Weinreb 酰胺）在 CO 2催化的转酰胺基反应中与 N 2相比表现出明显的反应性大气层。进行了比较 Hammett 研究和动力学分析，以阐明分子 CO 2的催化活化机制，这得到了 DFT 计算的支持。我们将CO 2在转酰胺基反应中的积极作用归因于通过与亲电子CO 2共价结合来稳定四面体中间体。

  日期：2016.10.7

  The “Y” donor group (Y = −OMe, −SEt, −PPh2, −NH2, −NMe2, −Py, pyrrolidinyl, quinolyl) of the pincer-type ruthenium complexes RuHCl(CO)[κ3-YNP] has a dramatic influence on the catalytic activity in the dehydrogenative homocoupling and cross-coupling of ethanol and ester hydrogenation reactions. The observations are connected with the mechanisms of the catalytic reactions, and this paper provides evidence
