  Novel compounds with potent CDK9 inhibitory activity for the treatment of myeloma

  摘要：

  Cyclin-dependent kinases (CDKs) and Polo-like kinases (PLKs) play key role in the regulation of the cell cycle. The aim of our study was originally the further development of our recently discovered polo-like kinase 1 (PLK1) inhibitors. A series of new 2,4-disubstituted pyrimidine derivatives were synthesized around the original hit, but their PLK1 inhibitory activity was very poor. However the novel compounds showed nanomolar CDK9 inhibitory activity and very good antiproliferative effect on multiple myeloma cell lines (RPMI-8226). (C) 2018 Elsevier Ltd. All rights reserved.

• An “On-Cycle” Precatalyst Enables Room-Temperature Polyfluoroarylation Using Sensitive Boronic Acids
  作者：Liye Chen、Haydn Francis、Brad P. Carrow

  DOI：10.1021/acscatal.8b00341

  日期：2018.4.6

  fluorinated arylboronic acid building blocks in cross-coupling has remained challenging, because of their acute base sensitivity. We report a general solution to this problem using a true catalytic intermediate, Pd(PAd3)(p-FC6H4)Br, as a uniquely effective “on-cycle” precatalyst that allows Suzuki–Miyaura coupling to occur much faster than even the most severe protodeboronation side reactions. Control of boron

  交叉偶联中使用氟化芳基硼酸结构单元仍然具有挑战性，因为它们具有敏锐的碱敏感性。我们报告了使用真正的催化中间体Pd（PAd 3）（p -FC 6 H 4）Br作为唯一有效的“循环”预催化剂，可以使Suzuki-Miyaura偶联发生的速度快得多的一般解决方案。即使是最严重的原去硼副反应。还发现控制活性酸形式和休眠酯形式之间的硼形态在平衡催化速率与试剂分解之间起着至关重要的作用。该方法与任何氟化模式，对碱不稳定的官能团以及一系列溴（杂）芳烃均兼容。

  products. Here, we show that solid-state high-temperature ball-milling conditions facilitate a palladium-catalyzed cross-coupling with polyfluorinated arylboronic acids and pinacol esters employing a simple catalytic system in the absence of any stoichiometric additives. This reaction exhibits a broad substrate scope and can be carried out in air, and the use of large amounts of dry and degassed organic solvents

  多氟化芳基硼亲核试剂和芳基卤化物之间的 Suzuki-Miyaura 交叉偶联能够有效构建有机材料和催化剂中常见的多氟化结构基序。与这种转化相关的一个关键挑战涉及弱亲核多氟化有机硼试剂的缓慢金属转移，这通常会降低偶联产物的产率。在这里，我们展示了固态高温球磨条件促进了钯催化与多氟化芳基硼酸和频哪醇酯的交叉偶联，在没有任何化学计量添加剂的情况下，采用简单的催化体系。该反应底物范围广，可在空气中进行，不需要使用大量干燥脱气的有机溶剂。
• “Cationic” Suzuki–Miyaura Coupling with Acutely Base-Sensitive Boronic Acids
  作者：Liye Chen、Daniel R. Sanchez、Bufan Zhang、Brad P. Carrow

  DOI：10.1021/jacs.7b07687

  日期：2017.9.13

  base-promoted protodeboronation of polyfluoroaryl and heteroaryl boronic acids complicates their use in Suzuki-Miyaura coupling (SMC) because a base is generally required for catalysis. We report a "cationic" SMC method using a PAd3-Pd catalyst that proceeds at rt in the absence of a base or metal mediator. A wide range of sensitive boronic acids, particularly polyfluoroaryl substrates that are poorly compatible

  多氟芳基和杂芳基硼酸的快速、碱促进的原脱硼使它们在 Suzuki-Miyaura 偶联 (SMC) 中的使用复杂化，因为催化通常需要碱。我们报告了一种使用 PAd3-Pd 催化剂的“阳离子”SMC 方法，该催化剂在没有碱或金属介体的情况下在室温下进行。各种敏感的硼酸，特别是与经典 SMC 条件相容差的多氟芳基底物，会发生干净的偶联。化学计量实验涉及有机钯阳离子的中介作用，它支持长期假定的 SMC 中金属转移的阳离子途径。
• Mechanistic Origins of Regioselectivity in Cobalt-Catalyzed C(sp2)-H Borylation of Benzoate Esters and Arylboronate Esters
  作者：Tyler P. Pabst、Linda Quach、Kaitlyn T. MacMillan、Paul J. Chirik

  日期：2021.1

  Synthetic and mechanistic investigations into the C(sp2)-H borylation of various electronically diverse arenes catalyzed by bis(phosphine)pyridine (iPrPNP) cobalt complexes are reported. Borylation of various benzoate esters and arylboronate esters gave remarkably high selectivities for the position para to the functional group; in both cases, this regioselectivity was found to override the ortho-to-fluorine

  报道了双（膦）吡啶 ( iPr PNP) 钴配合物催化的各种电子多样性芳烃的 C(sp 2 )-H 硼化反应的合成和机理研究。各种苯甲酸酯和芳基硼酸酯的硼化反应对官能团的对位产生了非常高的选择性；在这两种情况下，发现这种区域选择性覆盖了之前报道的 ( iPr PNP)Co 硼化催化剂的邻位到氟的区域选择性，这是由 C(sp 2 )-H 氧化加成的热力学控制引起的。机理研究支持导致对位到酯和对位的途径分别通过动力学控制 BH 和 C(sp 2 -H) 氧化加成对硼酸酯的选择性。一种特别缺电子的氟化芳基硼酸酯的硼化导致 C(sp 2 )-H 氧化加成的加速和伴随的区域选择性反转，表明催化循环各个步骤的相对速率的细微变化可以实现独特且可切换的位点选择性。
