  2,2-二叠氮基乙酰乙酸酯与胺的非常规反应

  摘要：

  我们发现 2,2-二叠氮基乙酰乙酸酯是一类具有基本未知反应性的化合物，可以通过一种不涉及任何试剂的新策略与胺偶联。2,2-二叠氮乙酸酯是碳-碳键断裂下的非常规离去基团。该反应导致酰胺键的构建，耐受各种官能度，并且在实验简单的条件下在多种溶剂中同样表现良好。我们还证明可以避免 2,2-二叠氮基酰基乙酸酯化合物的分离：在室温下在胺存在下用 (Bu4N)N3 和碘处理酰基乙酸酯时很容易碎裂。通过使用这种方法，具有各种结构基序的多种酰基乙酸酯被直接转化为酰胺。

  본 발명은 전이금속촉매의 존재 하에 알카인 및 N-하이드록시 화합물을 유기용매 내에서 교반하여 아마이드 결합을 형성시키는 단계를 포함하는 아마이드 화합물의 제조방법 및 이를 이용한 펩타이드 제조방법에 관한 것으로, 본 발명에 의한 아마이드화 반응은 기존의 단순한 친핵성 및 친전자성과 같은 극성 반응성에 의존하지 않고 알카인과 전이금속의 배위결합 반응성에서 도출된 반응을 기반으로 하여 탁월한 화학선택성을 나타낸다. 또한, 펩타이드 합성시 소모적인 보호기 부착 및 탈착 반응 단계를 필요로 하지 않고 반응공정이 간단하여 폴리펩타이드 계열의 화합물을 합성하는데 매우 효과적일 뿐 아니라 반응 도중 출발물질이 소실되지 않기 때문에 100%의 원자경제성을 갖는다.

  This invention relates to a method for producing amide compounds, which includes a step of stirring alkaline and N-hydroxy compounds in an organic solvent under the presence of a transition metal catalyst to form amide bonds, and a peptide production method using the same. The amide reaction according to the present invention is based on the reactivity derived from the coordination reaction between alkaline and transition metals, rather than relying on conventional polar reactions such as simple nucleophilic and electrophilic reactions, demonstrating excellent chemical selectivity. Furthermore, the peptide synthesis process does not require consuming protective group attachment and detachment reactions, and the reaction process is simple, making it very effective for synthesizing compounds in the polyamide series, while also maintaining 100% atom efficiency as the starting materials are not lost during the reaction.

  The ruthenium catalyzed selective sp(3) C-O cleavage with amide formation was reported in reactions of 3-alkoxy-1-propanol derivatives and amines. The cleavage only occurs at the C3-O position even with 3-benzyloxy-1-propanol. Based on the experimental results, O-bound and C-bound Ru enolate complexes were proposed as key intermediates for the unique selective sp(3) C-O bond cleavage in 3-alkoxy-1-propanols.
