Well‐defined ruthenium(II) biscarboxylate complexes enabled selective ortho‐deuteration with weakly‐coordinating, synthetically useful carboxylic acid with outstanding levels of isotopic labeling. The robust nature of the catalytic system was reflected by a broad functional group tolerance in an operationally‐simple manner, allowing the isotope labeling of challenging pharmaceuticals and bioactive heterocyclic
定义明确的双羧酸钌(II)配合物可实现选择性配位氘代反应,以及配位水平低,具有同位素标记水平的合成上有用的羧酸。催化系统的鲁棒性以操作简便的方式被广泛的官能团耐受性所反映,从而可以对具有挑战性的药物和生物活性杂环基序进行同位素标记。瑞格列奈(一种抗糖尿病药物)的选择性highlighted标记突出了我们方法的合成能力,使人们可以使用已定义的labeled标记的治疗剂。
