  A new approach to phosphoserine and phosphothreonine synthons suitable for the stepwise synthesis of phosphopeptides

  摘要：

  Several phosphoserine and phosphothreonine synthons suitable for the stepwise synthesis of phosphopeptides have been prepared. Treatment of methylthiomethyl (MTM) esters of either benzyloxycarbonyl (Z), tert-butyloxycarbonyl (Boc) and allyloxycarbonyl (Alloc) serine and / or threonine with phosphochloridate in pyridine, followed by MgBr2 cleavage of MTM in diethylether, afforded the title compounds in excellent yields.

• Phenylhydrazide as an Enzyme-Labile Protecting Group in Peptide Synthesis
  作者：Martin Völkert、Surrinder Koul、Gernot H. Müller、Manfred Lehnig、Herbert Waldmann

  DOI：10.1021/jo0259966

  日期：2002.10.1

  The enzymatic cleavage of amino acid phenylhydrazides with the enzyme tyrosinase (EC 1.14.18.1) offers a new, mild, and selective method for C-terminal deprotection of peptides. The advantages of the described methodology are the very mild oxidative removal of the protecting group at room temperature and pH 7, a high chemo- and regioselectivity, and the availability of the biocatalyst. Even in oxygen-saturated

  用酪氨酸酶（EC 1.14.18.1）酶解氨基酸苯酰肼为肽的C端脱保护提供了一种新的，温和的，选择性的方法。所述方法的优点是在室温和pH 7下非常温和的氧化去除保护基，高的化学和区域选择性以及生物催化剂的可用性。即使在氧气饱和的溶液中，也未观察到敏感蛋氨酸残基的氧化。这些特征使得该方法适合于敏感肽缀合物的合成。机理数据表明，氧化加合物的水解是通过自由基机理进行的。

• Palladium-catalyzed reaction of tributyltin hydride. Selective and very mild deprotection of allyl and allyloxycarbonyl derivatives of amino-acids.
  作者：F Guibe、O Dangles、G Balavoine

  DOI：10.1016/s0040-4039(00)84530-x

  日期：——

  Allyl(All) and Allyloxycarbonyl(Alloc) amino-acid derivatives are deprotected through palladium-catalyzed hydrostannolysis by Bu3SnH in a highly selective manner. Benzyl and benzyloxycarbonyl groups are stable under these conditions. Moreover the allyl and Alloc groups seem orthogonal to the t-butyl and t-butoxycarbonyl protecting groups.

  烯丙基（All）和烯丙氧基羰基（Alloc）氨基酸衍生物通过Bu 3 SnH以高选择性的方式通过钯催化的氢化锡烷基水解进行脱保护。苄基和苄氧羰基在这些条件下是稳定的。此外，烯丙基和Alloc基团似乎与叔丁基和叔丁氧羰基保护基团正交。

This synthesis utilizes the phosphoramidite method with allyl for the phosphate linkages and the C-terminal of the peptide and allyloxycarbonyl for the nucleoside bases and the N-terminal of the peptide. In this synthesis, the removal of the allylic protecting groups and the detachment of the products was achieved under

  已经完成了对碱基不稳定的核苷酸-肽结合物的有效合成，其中两个组分通过磷酸二酯键直接连接在核苷酸的末端羟基和肽的丝氨酸或苏氨酸残基的羟基之间。该合成利用亚磷酰胺方法，其中烯丙基用于肽的磷酸键和C-末端，烯丙氧基羰基用于肽的核苷碱基和N-末端。在该合成中，在非碱性或温和的碱性条件下实现了烯丙基保护基的去除和产物的分离，从而使不稳定的磷酸酯连接基不引起明显的分解，因此以高纯度获得了目标缀合物。高产。
