  eliminates various synthetic obstacles such as multi-step routes, low yields, and inseparable impurities. The described method comprises great potential to be implemented in automated combinatorial approaches by markedly facilitating the access to a variety of PBAs. The coupling of amino acids or other building blocks with α-aminoboronates allows the creation of hybrid molecules with significant potential

  The Ser, Cys, and His side chains play decisive roles in the syntheses, structures, and functions of proteins and enzymes. For our structural and biomedical investigations of β-peptides consisting of amino acids with proteinogenic side chains, we needed to have reliable preparative access to the title compounds. The two β3-homoamino acid derivatives were obtained by Arndt–Eistert methodology from Boc-His(Ts)-OH

  日期：2018.8.3

  A one-step preparation of 1,1-dimethylallyl (DMA) esters was optimized for the C-terminal protection of a range of Fmoc-protected amino acids. This preparation is not sensitive to the scale of reaction and affords the corresponding DMA esters in 70–99% yield with high regioselectivity. Additionally, these DMA-protected amino acids were used with the backbone amide linker (BAL) of Albericio and Barany

  优化了1，1-二甲基烯丙基（DMA）酯的一步制备方法，以保护一系列Fmoc保护的氨基酸的C端。该制备方法对反应规模不敏感，可以以70-99％的产率提供相应的DMA酯，并具有较高的区域选择性。此外，这些DMA保护的氨基酸与Albericio和BArany的骨架酰胺接头（BAL）一起使用，发现在合成三肽酯的过程中能抵抗二酮哌嗪的形成。C端DMA保护与BAL链接兼容，并允许在整个合成过程中使用基于Fmoc的标准方法。

  be deprotected with concomitant formation of a disulphide bond connecting the two Cys residues. A mechanistic study on the disulphide formation led to a general protocol for deprotection of the S-Acm group by CuSO4 and a 1,2-aminothiol under aerobic conditions. Application of this new deprotection reaction allowed for the synthesis of Apamin, a peptide with two-disulphides in a one-pot/stepwise disulphide-bridging
