  Structure–activity studies of 5-substituted pyridopyrimidines as adenosine kinase inhibitors

  摘要：

  The synthesis and SAR of a novel series of non-nucleoside pyridopyrimidine inhibitors of the enzyme adenosine kinase (AK) are described. It was found that pyridopyrimidines with a broad range of medium and large non-polar substituents at the 5-position potently inhibited AK activity. A narrower range of analogues was capable of potently inhibiting adenosine phosphorylation in intact cells indicating an enhanced ability of these analogues to penetrate cell membranes. Potent AK inhibitors were found to effectively reduce nociception in animal models of thermal hyperalgesia and persistent pain. (C) 2000 Elsevier Science Ltd. All rights reserved.

  可见光驱动的苯酚光氧化引发缺电子烯烃的环氧化反应以合成环氧二烯酮产品

  摘要：

  本文描述了从在间位带有缺电子烯烃的对位取代苯酚开始合成环氧二烯酮产品。这种一锅式光氧化/环氧化转化在室温下发生，在绿光照射下使用催化量的玫瑰红和碳酸铯。该反应提供了一系列功能化的环氧二烯酮产品，其非对映异构体比例从 4:1 到 >12:1。DFT 计算和机理实验表明，该反应将通过单线态氧介导的酚类光氧化反应进行，然后在烯烃侧臂上进行分子内氧原子转移。

• Selective Construction of C−C and C=C Bonds by Manganese Catalyzed Coupling of Alcohols with Phosphorus Ylides
  作者：Xin Liu、Thomas Werner

  日期：2021.2.16

  manganese catalyzed coupling of alcohols with phosphorus ylides. The selectivity in the coupling of primary alcohols with phosphorus ylides to form carbon‐carbon single (C−C) and carbon‐carbon double (C=C) bonds can be controlled by the ligands. In the conversion of more challenging secondary alcohols with phosphorus ylides the selectivity towards the formation of C−C vs. C=C bonds can be controlled by the

  在本文中，我们报道了锰与磷酰化物的锰催化偶联。伯醇与磷酰化物偶联形成碳碳单键（CC）和碳碳双键（C = C）的选择性可以通过配体控制。在更具挑战性的仲醇与磷酰化物的转化中，通过反应条件，即碱的量，可以控制形成CC与C = C键的选择性。偶联反应的范围和局限性通过21种醇和15种烷基化物的转化得到了彻底评估。值得注意的是，与基于贵金属络合物作为催化剂的现有方法相比，本催化体系基于富含稀土的锰催化剂。该反应也可以在顺序的一锅法反应中进行，该反应在锰催化的C-C和C = C键形成后就地生成磷叶立德。机理研究表明，CC键是通过借位氢途径生成的，而C = C键的形成遵循无受体的脱氢偶联途径。
