  1B inhibitors, 1H-pyrazolo[3,4-b]pyridine derivatives were synthesized. Mostly, 3-aryl-5-arylamino compounds (6) and 3,5-diaryl compounds (8 and 9) were prepared and especially, 3,5-diaryl compound 8 and 9 showed excellent DYRK1B inhibitory enzymatic activities with IC50 Values of 3–287 nM. Among them, 3-(4-hydroxyphenyl), 5-(3,4-dihydroxyphenyl)-1H-pyrazolo[3,4-b]pyridine (8h) exhibited the highest

  cornerstone method for sp2–sp2 cross-coupling in industry. There has been a concerted effort to enable the use of Ni catalysis as an alternative to Pd in order to mitigate cost and improve sustainability. Despite significant advances, ligand development for Ni-catalyzed Suzuki–Miyaura cross-coupling remains underdeveloped when compared to Pd and, as a consequence, ligands for Ni-catalyzed processes are typically

  Suzuki–Miyaura反应是sp 2 –sp 2的基石方法工业中的交叉耦合。为了降低成本和提高可持续性，已经做出了共同的努力以使得能够使用Ni催化来代替Pd。尽管取得了重大进展，但与Pd相比，Ni催化的Suzuki-Miyaura交叉偶联的配体开发仍不发达，因此，Ni催化过程的配体通常取自Pd舞台。在这项研究中，我们评估了以常见的双齿配体（dppf）为首对首形式使用相似的Ni和Pd预催化剂对联芳偶合的最常见类型的效果，建立了直接替代Pd的实际含义与Ni一起，并从机械角度确定这些观察的潜在起源。
