the heterocycle on a hydroxylated resin using zinc triflate. New Suzuki–Miyaura cross-coupling conditions are developed for the quantitative formation of the phenyl–phenyl bond. Our straightforward synthesis scheme, starting from the conserved phenyltetrazole moiety and ending with the appending of the structurally variable moiety, is well suited to the preparation of sartans and their analogues at
联苯四唑是公认的特权结构。其中,治疗上重要的一类sartan表现出对AT1受体的拮抗活性。我们已经开发了使用三氟甲磺酸锌通过杂环将四唑衍生物固定在羟基化树脂上的方法。开发了新的Suzuki-Miyaura交叉偶联条件以定量形成苯基-苯基键。我们简单的合成方案从保守的苯基四唑部分开始,到结构可变部分的末端结束,非常适合于在实验室规模下制备Sartans及其类似物。因此,我们在此描述了市售AT1拮抗剂厄贝沙坦的第一个固相合成。
