  亚磷酸盐自由基陷阱“BecaP”实现趋同脱硼和脱羧磷酸化

  摘要：

  碳磷键的形成在合成化学中具有重要意义，因为含磷化合物具有许多不可或缺的生化作用。虽然有多种方法可以获取有机磷化合物，但将易于获取的烷基进行膦酰化以形成脂肪族膦酸酯的情况很少见，并且在合成中并不常用。在此，我们介绍了一种新型磷自由基捕获剂“BecaP”，它能够在可见光光催化条件下轻松有效地对烷基自由基进行磷酰化。重要的是，BecaP 的两亲性质允许与亲核（通过单电子氧化激活）和亲电（通过单电子还原激活）烷基自由基前体发生氧化还原中性反应。因此，可以使用多种原料烷基三氟硼酸钾盐和氧化还原活性羧酸酯，每一类底物都通过不同的机制途径进行。温和的条件适用于将膦酸酯基序安装到药物和天然产物中，这一点通过巴氯芬（肌肉松弛剂）直接转化为苯氯芬（GABA B 拮抗剂）来证明。

  日期：——

  A photoredox-catalyzed C–H functionalization of heteroarenes using a variety of primary, secondary, and tertiary alkyltrifluoroborates is reported. Using Fukuzumi's organophotocatalyst and a mild oxidant, conditions amenable for functionalizing complex heteroaromatics are described, providing a valuable tool for late-stage derivatization. The reported method addresses the three major limitations of

  据报道，使用各种伯，仲和叔烷基三氟硼酸酯进行光氧化还原催化的杂芳烃的CH官能化。描述了使用Fukuzumi的有机光催化剂和温和的氧化剂，适合于功能化复杂杂芳族化合物的条件，为后期衍生化提供了有价值的工具。报告的方法解决了先前报道的光氧化还原介导的Minisci反应的三个主要局限性：（1）使用超化学计量的自由基前体，（2）反复选择性，以及（3）引入昂贵的光催化剂。另外，使用了许多前所未有的复杂烷基，从而增加了Minisci化学可利用的化学空间。为了展示后期功能化中的应用程序，合成了奎宁和喜树碱类似物。最后，进行了NMR研究以提供合理的杂芳基活化作用，该活化作用允许使用单当量的自由基前体，并且还提高了区域选择性。因此，在酸催化剂和BF 3的存在下观察到1 H和13 C NMR观察到独特的杂芳基物质。

  A photoredox catalytic method has been developed for the direct C2 alkylation of pyridine N-oxides. This reaction is compatible with a range of synthetically relevant functional groups for providing efficient synthesis of a variety of C2-alkylated pyridine N-oxides under mild conditions. Mechanistic studies are consistent with the generation of a radical intermediate along the reaction pathway.

The practical method provides yields up to 97% with excellent enantioselectivities up to 99% ee and can be classified as a redox neutral, electron-transfer-catalyzed reaction

  A rapid and highly selective oxidative cross-coupling reaction between readily available and shelf-stable arylboronic acids and primary or secondary potassium alkyltrifluoroborates was devised and developed, which works under mild conditions using copper(II) acetate as the catalyst and silver oxide as the oxidant. Initial experimental results indicate that a single-electron transmetalation process

  日期：2020.7.2

  A silver-catalyzed trifluoromethoxylation of alkyl trifluoroborates with trifluoromethyl arylsulfonate as the trifluoromethoxylation reagent has been reported for the first time. This reaction is performed under mild reaction conditions and has wide functional group compatibility. In addition, the mechanism of this site-specific trifluoromethoxylation is proposed as a radical pathway.
