  摘要：

  具有羟甲基官能团的 2,5-二酮哌嗪 (DKP) 是许多生物活性分子和功能材料中的必需结构。我们已经建立了一个简单的协议，用于通过二硼酸酐催化的羟基定向肽键形成简明合成此类 DKP。本报告中的连续反应由三个步骤组成，其中水是唯一的副产物的分子间催化缩合反应、氮保护基团的简单脱保护和分子内环化，使功能化 DKPs 的合成成为可能。无需任何中间纯化即可获得优异的产量。该协议的效用已通过合成天然产物、phomamide 和 Cyclo(Deala- l -Leu) 得到证明。

  摘要：

• Umpolung reactivity in amide and peptide synthesis
  作者：Bo Shen、Dawn M. Makley、Jeffrey N. Johnston

  DOI：10.1038/nature09125

  日期：2010.6

  which the polarities of the two reactants are reversed (German, umpolung) during carbon–nitrogen bond formation relative to traditional approaches. The use of nitroalkanes as acyl anion equivalents provides a conceptually innovative approach to amide and peptide synthesis, and one that might ultimately provide for efficient peptide synthesis that is fully reliant on enantioselective methods.

  酰胺键是自然界最常见的功能和结构元素之一，因为所有天然肽和蛋白质的骨架都由酰胺键组成。酰胺也存在于许多治疗性小分子中。使用现有方法构建酰胺键主要依赖于脱水方法，尽管氧化和基于自由基的方法是代表性的替代方法。在几乎每个例子中，在碳-氮键形成步骤中，碳和氮分别具有亲电和亲核特性。在这里，我们表明用亲电碘源活化胺和硝基烷烃可以直接产生酰胺产物。初步观察支持两种反应物极性反转的机制（德国，umpolung) 在碳氮键形成过程中相对于传统方法。使用硝基烷烃作为酰基阴离子等价物为酰胺和肽合成提供了一种概念上的创新方法，并且可能最终提供完全依赖对映选择性方法的有效肽合成。

  A stereoconservative three-step synthesis to access to 1,2,4-oxadiazine-3,6-dione is presented. This underexplored platform could be considered as a constrained oxy-azapeptide or an aza-diketomorpholine, the methodology being then successfully applied to produce enantiopure aza-analogs of diketomorpholine natural products. Importantly, the first crystal structures were obtained and compared to diketomorpholine

  Imines of α-amino acid esters with aromatic, heterocyclic, and aliphatic aldehydes generate azomethine ylides stereospecifically by a prototropic shift on heating in toluene. The azomethine ylides undergo cycloaddition to N-phenylmaleimide, maleic anhydride, and p-naphthoquinone via an endo-transition state to give racemic, single diastereoisomeric, cycloadducts. α-Amino acids undergo analogous cycloadditions
