• Generation and Alkylation of α-Carbamyl Radicals via Organic Photoredox Catalysis

  Strategies for the direct C-H functionalization of amines are valuable as these compounds comprise a number of pharmaceuticals, agrochemicals and natural products. This work describes a novel method for the C-H functionalization of carbamate-protected secondary amines via α-carbamyl radicals generated using photoredox catalysis. The use of the highly oxidizing, organic acridinium photoredox catalyst

  胺的直接 CH 官能化策略很有价值，因为这些化合物包括许多药物、农用化学品和天然产品。这项工作描述了一种通过使用光氧化还原催化产生的 α-氨基甲酰基自由基对氨基甲酸酯保护的仲胺进行 CH 官能化的新方法。使用高氧化性有机吖啶光氧化还原催化剂可以直接氧化具有高氧化还原电位的氨基甲酸酯保护的胺，得到相应的氨基甲酰基阳离子自由基。去质子化后，所得的开壳物质可以被各种迈克尔受体截获，得到精心设计的 α-官能化仲胺。该反应在温和的条件下进行，不需要外源氧化还原介质或底物预官能化。此外，

  作者：Adel M. ElSohly、Daniel A. Wespe、Tyler J. Poore、Scott A. Snyder

  Folding it all together: Most of the syntheses developed for the securinega alkaloid class require lengthy sequences to create their bridging butenolide domains. A novel approach uses N‐heterocyclic carbenes (NHCs) and Lewis acids to forge the entire domain in a single step from appropriate precursors, showing that ynal‐derived homoenolates can participate as nucleophiles in intramolecular settings (see scheme)

  放在一起：为securinega生物碱类开发的大多数合成都需要很长的序列才能形成它们的桥接丁烯内酯结构域。一种新颖的方法使用N杂环卡宾（NHC）和Lewis酸一步一步地从合适的前体中锻造整个结构域，这表明合成来源的均烯酸酯可以亲核体的形式参与分子内环境（请参见方案）。

  a synthetic challenge because of the remote and unactivated nature of β-C–H bonds in these motifs. Herein, we demonstrate the β-functionalization of saturated aza-heterocycles enabled by a two-step organic photoredox catalysis approach. Initially, a photoredox-catalyzed copper-mediated dehydrogenation of saturated aza-heterocycles produces ene-carbamates. This is followed by an anti-Markovnikov hydrofunctionalization

  由于这些基序中 β-C-H 键的远程和未活化性质，饱和氮杂杂环的直接 β-官能化仍然是一个合成挑战。在此，我们展示了通过两步有机光氧化还原催化方法实现的饱和氮杂杂环的β-功能化。最初，光氧化还原催化的铜介导的饱和氮杂杂环脱氢产生烯氨基甲酸酯。然后用一系列含杂原子的亲核试剂对烯氨基甲酸酯进行反马尔科夫尼科夫加氢功能化，在 β 位提供一系列 C-C、C-O 和 C-N 氮杂杂环。
