  摘要：

  The ATR pathway is a critical mediator of the replication stress response in cells. In aberrantly proliferating cancer cells, this pathway can help maintain sufficient genomic integrity for cancer cell progression. Herein we describe the discovery of 19, a pyrazolopyrimidine-containing inhibitor of ATR via a strategic repurposing of compounds targeting PI3K. (C) 2017 Elsevier Ltd. All rights reserved.

  铱催化的杂芳烃的 C-H 硼化：范围、区域选择性、后期功能化的应用和机制

  摘要：

  报道了铱催化杂芳烃的 CH 硼化的研究。发现几种含有多个杂原子的杂芳烃适合由铱 (I) 前体和四甲基菲咯啉的组合催化的 CH 硼化。对反应范围的研究导致了预测硼化的区域选择性的强大规则的发展，其中最重要的是硼化发生在氮原子的远端。报告了原位形成的杂芳基硼酸酯的一锅官能化，证明了所报告的方法对合成复杂杂芳基结构的有用性。还展示了这种方法在生物活性化合物的合成和后期功能化中的应用。机理研究表明，碱性杂芳烃可以与催化剂结合，并将在芳烃硼化过程中观察到的烯烃结合复合物的静止状态改变为含有结合杂芳烃的物质，从​​而导致催化剂失活。对观察到的区域选择性起源的研究表明，由于快速的 NH 硼酸化，硼酸化发生在 NH 键的远端，为与这些键相邻的硼酸化创造了不利的空间环境。计算研究和机理研究表明，与碱性氮相邻的 CH 键缺乏可观察到的硼化并不是在 CH 活化之前与庞大的路易斯酸配位的结果，
