  bearing other substituents such as a bromine atom and alkenyl, succinimide, and carbonyl groups, were prepared, and their reactions with samarium diiodide or tributylstannane were studied. The reactions of acyl silanes occurred in various manners such as reductions, reductive alkylations, intramolecular radical cyclizations, pinacol couplings, aldol reactions, and Tishchenko reactions, depending on the nature

  anticancer activity of SR9243 (7) and this suggests that new inverse agonists have great potential as anticancer agents. We identified compounds with distinct selectivity toward both LXR isoforms, which can be excellent tools to study the pharmacology of both isoforms. We employed molecular dynamic (MD) simulations to better understand the molecular mechanism underlying inverse agonist activity and to

• 9-Silafluorenyl Dichlorides as Chemically Ligating Coupling Agents and Their Application in Peptide Synthesis
  作者：Samuel J. Aspin、Sylvain Taillemaud、Patrick Cyr、André B. Charette

  DOI：10.1002/anie.201606120

  日期：2016.10.24

  A fundamentally simple, mild, and practical procedure for peptide bond formation is reported that employs a stoichiometric amount of easy‐to‐access 9‐silafluorenyl dichlorides as the coupling agent. Without initial preactivation or elaboration of the carboxylic acid or amine termini of the amino acids, the developed reagent is proposed to act through an unprecedented chemical ligation mechanism, bringing

  据报道，一种基本简单，温和且实用的肽键形成方法是采用化学计量的易于获得的9-二氟芴基二氯化物作为偶联剂。无需对氨基酸的羧酸或胺末端进行初步的预活化或精加工，就可以开发出一种通过空前的化学连接机制发挥作用的试剂，从而将两个偶联配偶体聚集在一起，然后再将其消除。因此以高收率和低至无差向异构化提供所需的酰胺或肽键。
• Scalable anti-Markovnikov hydrobromination of aliphatic and aromatic olefins
  作者：Marzia Galli、Catherine J. Fletcher、Marc del Pozo、Stephen M. Goldup

  DOI：10.1039/c6ob00692b

  日期：——

  To improve access to a key synthetic intermediate we targeted a direct hydrobromination-Negishi route. Unsurprisingly, the anti-Markovnikov addition of HBr to estragole in the presence of AIBN proved successful. However, even in the absence of an added initiator, anti-Markovnikov addition was observed. Re-examination of early reports revealed that selective Markovnikov addition, often simply termed

  为了改善获得关键合成中间体的途径，我们的目标是直接进行氢溴化-根岸路线。毫不奇怪，在AIBN的存在下，将溴化氢在马齿中添加反马尔可夫尼可夫成功。然而，即使在没有添加引发剂的情况下，也观察到了反马尔科夫尼科夫的加入。对早期报道的重新检查表明，除非排除了空气，否则在溴化氢中并不总是观察到选择性马尔科夫尼科夫加法，通常简称为“正常”加法，导致重新发现了可重现且可扩展的无引发剂方案。
