• Synthesis and Properties of Aminoacylamido-AMP:  Chemical Optimization for the Construction of an <i>N</i>-Acyl Phosphoramidate Linkage

  This paper describes the design and synthesis of a new type of aminoacyl-adenylate analogue (aa-AMPN) having an N-acyl phosphoramidate linkage where the oxygen atom of the mixed anhydride bond of aminoacyl-adenylate (aa-AMP) is replaced by an amino group. This new type of aa-AMP analogue is expected to be useful as material for studies on the recognition mechanism of the aminoacylation of tRNA and

  本文介绍了具有N-酰基氨基磷酸酯键的新型氨基酰基-腺苷酸类似物（aa-AMPN）的设计和合成，其中氨基酰基-腺苷酸（aa-AMP）的混合酸酐键的氧原子被氨基。这种新型的aa-AMP类似物有望用作研究tRNA氨基酰化和其他生化反应识别机制的材料。羧酰胺的亚磷酰胺衍生物与核苷衍生物的缩合失败，因为活化的亚磷酰胺衍生物不仅与羟基反应，而且与另一种反应性物质反应。通过5'-O-亚磷酰胺基腺苷衍生物与羧酰胺衍生物的反应研究了另一种方法。选择TBTr和TSE基团分别用于保护氨基酸酰胺的氨基和磷酸基。详细研究表明，使用5-（3,5-二硝基苯基）-1H-四唑作为亚磷酰胺的活化催化剂可在10分钟内迅速缩合，从而得到完全保护的aa-AMPN衍生物。没有发生副反应。通过两步程序对这些产物进行脱保护，得到高产率的aa-AMPN衍生物。还证明由此获得的aa-AMPN在酸性和碱性条件下均是稳定的，例如0.1M HCl（pH

  Amides formation from protected amino acids and peptides was achieved in an easy and convenient one-pot procedure using di-tert-butyl pyrocarbonate as activating agent in the presence of pyridine and ammonium hydrogencarbonate. The method gave good yields and did not induce racemization during the amidation of urethane protected amino acids.
