  Potassium Boc-Protected Secondary Aminomethyltrifluoroborates: Synthesis and Suzuki–Miyaura Cross-Coupling Reactions

  摘要：

  Seven potassium Boc-protected secondary aminomethyltrifluoroborates were prepared in a standardized two-step process. The Suzuki-Miyaura cross-coupling reaction was studied with this new class of nucleophiles, and a large variety of aryl and hetaryl chlorides provided the desired products in good to excellent yields, thereby allowing easy access to secondary aminomethyl substructures.

  current approaches to these important building blocks typically rely on oxidative processes, which might lead to issues such as lack of product diversity and functional group compatibility. Here, we report the design and utilization of 2-(BMIDA) acrylaldehyde as a suitable coupling partner toward photoredox-catalyzed intermolecular radical addition reaction for the rapid synthesis of functionalized α-boryl

  稳定的α-硼醛是重要的两性合成中间体，是有机合成的关键。然而，目前这些重要构建模块的方法通常依赖于氧化过程，这可能会导致缺乏产品多样性和官能团兼容性等问题。在这里，我们报道了 2-(BMIDA) 丙烯醛作为光氧化还原催化分子间自由基加成反应的合适偶联伙伴的设计和利用，以快速合成官能化 α-硼醛。使用市售光催化剂和易于获得的烷基三氟硼酸盐作为自由基前体，获得了各种 α-硼醛，收率高达 90%。初步机理研究表明该反应可能通过分子间自由基加成和自由基-极性交叉过程进行。通过放大反应、几次合成转化和生物活性分子的衍生化，进一步证明了该方法的合成潜力。此外，通过简单地将自由基前体转换为α-氨基酸，可以通过分子间自由基加成/环化序列获得不同的4-硼基2,3-二氢吡咯。此外，当使用相应的β-或γ-氨基酸时，也可以容易地获得含硼酸MIDA的六元或七元杂环。该策略为功能化α-硼基醛或硼基化杂环提供了一种简便

  日期：2013.5.17

  Sulfamates were studied as the electrophilic partners in the palladium-catalyzed Suzuki-Miyaura cross-coupling reaction with potassium Boc-protected primary and secondary aminomethyltrifluoroborates. A broad range of substrates was successfully coupled to provide the desired products. Complex molecules containing a new carbon-carbon bond and an aminomethyl moiety could be prepared through this developed method.
