  procedure for peptide‐bond formation is reported. Instead of activation of the carboxylic acid functionality, the reaction involves an unprecedented use of activated α‐aminoesters. The method provides a straightforward entry to dipeptides and was effective when a sensitive cysteine residue was used, as no epimerization was detected in this case. The applicability of this method to iterative peptide synthesis

  correlate with the natural product. The approach enlists a powerful Pd(0)-mediated indole annulation for the key macrocyclization of the complex core peptide, utilizes an underdeveloped class of hypervalent iodine(III) aryl substrates in a palladium-catalyzed C-H activation/β-arylation reaction conducted on a lysine derivative, and provides access to material with which the role of streptide and related

  Streptide (1) 是一种肽衍生的大环天然产物，自 2015 年发现以来引起了广泛关注。它包含前所未有的翻译后修饰，将残基 2 赖氨酸的 β-碳 (C3) 与残基的 C7 进行分子内连接。残基 6 色氨酸，从而形成 20 元环肽。在此，我们报告了第一个链肽的全合成，它证实了赖氨酸-色氨酸交联的区域化学，并提供了赖氨酸-2 C3 中心的立体化学（3R 与 3S）的明确分配。3R 和最初指定的 3S 赖氨酸非对映异构体都是通过全合成独立制备的，发现与天然产物相关的是前者，而不是后者。

  The synthesis of dipeptides through a sequential one‐pot procedure from commercially available protected amino acids is described. The transformation relies on the use of in situ generated transiently CDI‐protected α‐amino esters (CDI, e.g. N,N′‐carbonyldiimidazole). In addition of being a highly atom‐economical process, the couplings take place under very mild and neutral conditions without adding

  描述了通过顺序的一锅法从市售受保护的氨基酸合成二肽的方法。转化依赖于使用原位生成的瞬时CDI保护的α-氨基酯（CDI，例如N，N'-羰基二咪唑）。除了是高度原子经济的过程外，偶联还可以在非常温和和中性的条件下进行，而无需在反应介质中添加碱。该方案为二肽衍生物的制备提供了一条简洁且成本较低的途径（12个实例，收率高达87％），并且与常用的N-氨基甲酸酯保护基团兼容。此外，即使使用敏感的Boc-Cys（Bn）-OH，也未检测到差向异构。
