  醌和富烯之间的催化不对称[2 + 2]环加成反应以及随后的立体选择性异构化为2,3-二氢苯并呋喃

  摘要：

  通过使用手性铜（II）络合物催化剂，首次实现了醌与富烯之间的催化对映选择性[2 + 2]环加成反应。该转化以良好的产率提供了一系列对映异构体富集的[6,4,5]-三环环丁烷衍生物，具有优异的区域选择性和立体选择性。此外，[2 + 2]加合物可以轻松有效地和立体选择性地转化为正式的[3 + 2]加合物。

  Transition Metal-Free Direct C–H Functionalization of Quinones and Naphthoquinones with Diaryliodonium Salts: Synthesis of Aryl Naphthoquinones as β-Secretase Inhibitors

  摘要：

  A novel ligand-free, transition metal-free direct C-H functionalization of quinones with diaryliodonium salts has been developed for the first time. The transformation was promoted only through the use of a base and gave aryl quinone derivatives in moderate to good yields. This methodology provided an effective and easy way to synthesize β-secretase inhibitors. The radical trapping experiments showed that this progress was the radical mechanism.

• Synthesis of Aryl- and Alkylquinones through Rhodium-Catalyzed C–C ­Coupling under Mild Conditions

  日期：——

  A direct arylation, alkylation of quinones with aryl and alkyl boronic acids through rhodium-catalyzed C-C coupling has been developed under mild conditions. [Cp*RhCl2](2) was shown to be the most effective catalyst for the transformation. More importantly, good to excellent yields were obtained under room temperature and base-free conditions. This reaction provides a practical, efficient method for the synthesis of aryl- and alkylquinones.

  Ir-catalyzed arylation, alkylation of quinones with boronic acids was developed under room temperature. Both aryl and alkyl boronic acids are suitable for this transformation. This expands the application scope of the iridium catalyst. This is also an excellent proof that iridium catalysts can be used in the C-C coupling of quinones and naphthoquinones with alkyl boronic acids. (C) 2015 Elsevier B. V. All rights reserved.

  The present invention concerns methods and compositions involving inhibitors and enhancers of RAD51, a protein involved in homologous recombination. In some embodiments, the present invention concerns methods for stimulating homologous recombination, which has a number of significant research and clinical applications. In certain other embodiments, there are methods for protecting cells using a compound that enhances RAD51 activity. Such enhancers may also be employed to prevent or reduce damage to cells that may be caused by DNA damaging agents. In other embodiments, there are methods for sensitizing cells to the effects of DNA damaging agents, which can have particular applications for cancer patients. In some embodiments of the invention, the RAD51 enhancer or inhibitor is a small molecule that directly affects RAD51 activity, such as its ability to promote filament formation.
