  Convenient Synthesis of Valsartan via a Suzuki Reaction

  摘要：

  本文介绍了血管紧张素 II 抑制剂缬沙坦（Diovan）的高效合成方法。芳基芳基键的形成是其合成的关键步骤，该步骤是通过硼酸芳基酯与 2-溴苯基噁唑啉的铃木偶联完成的，具有良好的收率和纯度。这种方法克服了以前报道的合成方法的许多缺点。

  Improved Synthesis of Valsartan via Nucleophilic Aromatic Substitution on Aryloxazoline

  摘要：

  A highly efficient approach to the synthesis of the angiotensin II receptor antagonist valsartan (Diovan), one of the most important agents used in antihypertensive therapy today is described. The formation of the aryl-aryl bond represents the key step of its synthesis, which has been done by simple nucleophelic aromatic substitution on aryloxazoline with good yield and purity.
