  Improved Solid-Phase Peptide Synthesis Method Utilizing α-Azide-Protected Amino Acids

  摘要：

  [GRAPHICS]Pure alpha -azido acids were prepared using an efficient diazo transfer method followed by buffered workup, These building blocks were used to prepare small peptides on Wang resin by two approaches, Peptides prone to diketopiperazine formation were prepared in good yields by coupling acids to resin bound iminophosphoranes during Fmoc-Wang synthesis, The iminophosphoranes can also be hydrolyzed under neutral conditions to provide unprotected amines ready for further coupling.

  (R)-2-Azidoesters and their derived (R)-2-azido acids are readily prepared from common amino acids by an inversion methodology that employs (S)-2-nosyloxyesters as key intermediates. The (R)-2- azidoesters can be used as protected amino acid equivalents in peptide synthesis. Basic hydrolysis frees the carboxyl group. Triphenylphosphine/water is used to free the amine group. By these reactions a variety

  （R）-2-叠氮基酯及其衍生的（R）-2-叠氮基酸易于通过使用（S）-2-壬氧基氧基酯作为关键中间体的转化方法从普通氨基酸制备。（R）-2-叠氮基酯可以在肽合成中用作保护的氨基酸当量。碱性水解释放出羧基。三苯膦/水用于释放胺基。通过这些反应，可以容易地以良好的产率制备多种L-D和DL二肽，LDL三肽和二肽肽，而没有可检测的差向异构。
