  Staudinger Ligation:  A Peptide from a Thioester and Azide

  摘要：

  The technique of native chemical ligation enables the total chemical synthesis of proteins. This method is limited, however, by an absolute requirement for a cysteine residue at the ligation juncture. Here, this restriction is overcome with a new chemical ligation method in which a phosphinobenzenethiol is used to link a thioester and azide. The product is an amide with no residual atoms.

  see text] The Staudinger ligation can be used to couple a peptide with a C-terminal phosphinothioester to another with an N-terminal alpha-azido group to form a single peptide that contains no residual atoms. Here diphenylphosphinomethanethiol thioesters are shown to give high isolated yields for this transformation. This finding provides precedent for a powerful and versatile new method for the total

  [Staudinger连接]可用于将具有C端膦硫代磷酸酯的肽与具有N端α-叠氮基的另一种肽偶联，以形成不含残留原子的单个肽。此处显示二苯基膦基甲硫醇硫酯可为该转化提供高分离产率。该发现为蛋白质的全面合成提供了一种功能强大且用途广泛的新方法的先例。

  A method for generating a radiolabeled tracer. The method includes providing a phosphine molecule having at least one carbocyclic, aromatic, or pyrrolidinyl ring with an OH substitute. The OH of this phosphines molecule is then condensed with an acid to produce a phosphine ester. Staudinger ligation is then performed to generate the radiolabeled tracer by treating the phosphine ester with a radiolabeled azide having a PET radioisotope moiety.
