  N-Urethane-Protected Amino Alkyl Isothiocyanates: Synthesis, Isolation, Characterization, and Application to the Synthesis of Thioureidopeptides

  摘要：

  Synthetically useful N-Fmoc amino-alkyl isothiocyanates have been described, starting from protected amino acids. These compounds have been synthesized in excellent yields by thiocarbonylation of the monoprotected 1,2-diamines with CS2/TEA/p-TsCl, isolated as stable solids, and completely characterized. The procedure has been extended to the synthesis of amino alkyl isothiocyanates from Boc- and Z-protected amino acids as well. The utility of these isothiocyanates for peptidomimetics synthesis has been demonstrated by employing them in the preparation of a series of dithioureidopeptide esters. Boc-Gly-OH and Boc-Phe-OH derived isothiocyanates 9a and 9c have been obtained as single crystals and their structures solved through X-ray diffraction. They belong to the orthorhombic crystal system, and have a single molecule in the asymmetric unit (Z' = 1). 9a crystallizes in the centrosymmetric space group Pbca, while 9c crystallizes in the noncentrosymmetric space group P2(1)2(1)2(1).

  施陶丁格/氮杂Wittig反应来访问Ñ β -保护的氨基烷基异硫氰酸酯†

  摘要：

  一种统一的方式来访问Ñ β -保护的氨基烷基异硫氰酸酯使用Ñ β描述了通过Staudinger / aza-Wittig反应的一般策略保护的氨基烷基叠氮化物。用于获得异硫氰酸酯的方案的类型取决于前体的可用性，尤其是在氨基酸化学中，还取决于其他不稳定基团对方案中所用试剂的行为。幸运的是，我们并不担心这两个因素，因为通过标准方案可以轻松制备前体叠氮化物，并且本方案可以为访问标题化合物铺平道路，而不会影响Boc，Cbz和Fmoc保护基以及苄基和叔丁基。侧链。本策略消除了使用胺来获得标题化合物的需要，因此，该方法是分步经济的。其他优点包括保留手性，方便处理和易于纯化。还制备了一些迄今未报告的化合物，所有最终化合物均通过IR，质量，旋光度和1 H和13 C NMR研究。

  A unified approach to access Nβ-protected amino alkyl isothiocyanates using Nβ-protected amino alkyl azides through a general strategy of Staudinger/aza-Wittig reaction is described. The type of protocol used to access isothiocyanates depends on the availability of precursors and also, especially in the amino acid chemistry, on the behavior of other labile groups towards the reagents used in the protocols;
