most inexpensive procedure for chemical synthesis of enantiomerically pure phenylalanine. As a source of chirality, we use the ultimately inexpensive chiral auxiliary, 1-(phenyl)ethylamine, incorporated into the specially designed ligands which form the corresponding intermediate Ni(II) complexes with racemic phenylalanine. Diastereomerically pure Ni(II) complexes, containing either (S)- or (R)-phenylalanine
在这里,我们报告了对映体纯苯丙氨酸化学合成的最便宜的程序。作为手性的来源,我们使用最终廉价的手性助剂1-(苯基)乙胺,将其掺入经过特殊设计的配体中,这些配体与消旋苯丙氨酸形成相应的中间体Ni(II)配合物。将含有(S)-或(R)-苯丙氨酸的非对映体纯的Ni(II)配合物拆解以产生对映体纯的靶氨基酸,同时回收手性配体。所有反应均在操作方便的条件下进行,具有很高的收率,因此强调了该方法有吸引力的成本结构。
