  摘要：

  二烷基硼烷和氨基硼氢化物是温和的，选择性的还原剂，可与常用的酰胺还原剂互补，例如氢化铝锂（LiAlH 4）和氢化二异丁基铝（DIBAL）试剂。使用1或2当量的各种二烷基硼烷还原叔酰胺。叔酰胺的还原需要2当量的9-borabicyclo [3.3.1]壬烷（9-BBN）才能完全还原，得到相应的叔胺。一当量的位阻二亚氨基硼烷与叔酰胺反应，得到相应的醛。氨基硼氢化物是用于还原叔酰胺的有力且选择性的还原剂。二甲基氨基硼氢化锂和二异丙基氨基硼氢化锂由n-丁基锂和相应的胺-硼烷。通过二甲基胺-硼烷与甲基氯化镁的反应制得二甲基氨基硼氢化氯镁（ClMg + [H 3 B-NMe 2 ] -，MgAB）。氨基硼氢化物的溶液根据脂族叔胺和所用氨基硼氢化物的空间要求，将脂族，芳族和杂芳族叔酰胺还原为相应的醇，胺或醛。

  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。
