  摘要：

  金催化形成烯丙基硫中间体所利用的硫 - 克莱森重排使跳过的 1,4-二烯合成具有特殊水平的区域和对映控制。然而，由于肉桂基阳离子的广泛解离，迄今为止，肉桂基硫醚衍生物在硫-克莱森重排中的应用一直没有成功。通过微调双膦配体，我们能够使肉桂基硫醚参与 [3,3]-σ 重排，以高度对映选择性的方式并以良好的产率提供所需的 1,4-二烯。所得产物可转化为具有乙烯基部分的光学活性 2-色满酮和 4 H-色烯。

  Discovery of Potent Benzofuran-Derived Diapophytoene Desaturase (CrtN) Inhibitors with Enhanced Oral Bioavailability for the Treatment of Methicillin-Resistant Staphylococcus aureus (MRSA) Infections

  摘要：

  Blocking the staphyloxanthin biosynthesis process has emerged as a new promising antivirulence strategy. Previously, we first revealed that CrtN is a druggable target against infections caused by pigmented Staphylococcus aureus (S. aureus) and that naftifine was an effective CrtN inhibitor. Here, we identify a new type of benzofuran-derived CrtN inhibitor with submicromolar IC50 values that is based on the naftifine scaffold. The most potent analog, 5m, inhibits the pigment production of S. aureus Newman and three MRSA strains, with IC50 values of 0.38-5.45 nM, without any impact on the survival of four strains (up to 200 mu M). Notably, compound 5m (1 mu M) could significantly sensitize four strains to immune clearance and could effectively attenuate the virulence of three strains in vivo. Moreover, 5m was determined to be a weak antifungal reagent (MIC > 16 mu g/mL). Combined with good oral bioavailability (F = 42.2%) and excellent safety profiles, these data demonstrate that 5m may be a good candidate for the treatment of MRSA infections.

  Trifluoromethylation: The treatment of allylic halides with trifluoromethyltrimethylsilane in the presence of a catalytic amount of copper(I) thiophene‐2‐carboxylate (CuTC) gives the corresponding allylic trifluoromethylation products in good to high yields and with complete regioselectivity (see scheme). The use of THF as a solvent is crucial for obtaining good yields of product.

  silyloxypyrone-based (5 + 2) cycloadditions was determined to be extremely dependent on the nature of the dipolarophile. Neutral alkenes were the least reactive, whereas both electron-deficient and electron-rich dipolarophiles were more reactive, thus providing evidence for ambident oxidopyrylium intermediates. Qualitative rate studies, Hammett linear free energy relationships, and theoretical calculations combined

  基于甲硅烷氧基吡喃酮的 (5 + 2) 环加成的反应途径被确定为极其依赖于偶极试剂的性质。中性烯烃的反应性最低，而缺电子和富电子的偶极分子反应性更强，从而为氧化吡啶中间体的存在提供了证据。定性速率研究、Hammett 线性自由能关系和理论计算相结合，为通过协调和逐步边界的一系列反应性提供了证据。

• Enantioselective Sulfonium–Claisen Rearrangement with Cinnamyl Thioethers

  日期：2023.6.2

  Sulfonium–Claisen rearrangement leveraged by the gold-catalyzed formation of allyl sulfonium intermediates has enabled an exceptional level of regio- and enantiocontrol for the synthesis of skipped 1,4-dienes. However, the application of cinnamyl thioether derivatives to the sulfonium–Claisen rearrangement has been unsuccessful so far due to the extensive dissociation of the cinnamyl cation.
