  摘要：

  通过使用闭环吸附顶空装置（CLSA）收集了由海洋Roseobacter类细菌Rugeria pomeroyi释放的挥发性物质，并通过GC-MS进行了分析。发现了几种内酯，根据它们的质谱推导出了结构建议，并通过合成参考化合物进行了明确验证。进行了两种示范性内酯的对映选择性合成，以通过对映选择性GC-MS分析确定天然产物的对映构成。将内酯进行生物测试，以研究其对几种细菌、真菌和藻类的活性。观察到了特定的杀藻活性，这可能在细菌与藻类寄主之间的相互作用中起重要作用，尤其是在褪色藻类水华中。

• Photoredox-enabled 1,2-dialkylation of α-substituted acrylates <i>via</i> Ireland–Claisen rearrangement

  for the synthesis of valuable tertiary carboxylic acids by merging Giese-type radical addition with an Ireland–Claisen rearrangement. Key to success is the utilization of the reductive radical-polar crossover concept under photocatalytic reaction conditions to force the [3,3]-sigmatropic rearrangement after alkyl radical addition to allyl acrylates. Using readily available alkyl boronic acids as radical

  在本文中，我们报告了通过合并Giese型自由基加成物与Ireland-Claisen重排而合成的简单原料丙烯酸酯的1,2-二烷基化，以合成有价值的叔羧酸。成功的关键是在光催化反应条件下利用还原性自由基-极性交叉概念来强迫在将烷基自由基加成丙烯酸烯丙酯后强制[3,3]-σ重排。使用容易获得的烷基硼酸作为自由基祖细胞，该氧化还原中性，无过渡金属的方案允许轻度形成两个C（sp 3）–C（sp 3）键，因此只需一步即可快速获得复杂的叔羧酸。此外，当将α-甲硅烷基胺用作自由基前体时，这种策略能够高效合成高度有吸引力的α，α-二烷基化γ-氨基丁酸（GABA）–在相关转化中仍无法获得的结构性基序。根据自由基前体的性质及其固有的氧化电势，建议采用光氧化还原诱导的自由基链或单独的光氧化还原机理。
