  reported. Here we report a novel reaction of diazo compounds utilizing a radical-mediated addition strategy to achieve difunctionalization of diverse alkenes. Diazo compounds are transformed to carbon radicals with a photocatalyst or an iron catalyst through PCET processes. The carbon radical selectively adds to diverse alkenes delivering new carbon radical species, then forms products through hydroalkylation

  重氮化合物与烯烃最常见的反应之一是通过金属卡宾或游离卡宾中间体发生的环丙烷化反应。烯烃与重氮化合物的替代官能化是有限的，并且还没有通过碳碳双键添加 Z-CHR2 元素（Z = H 或杂原子，CHR2 源自 N2 = CR2）的方法报道。在这里，我们报告了一种利用自由基介导的加成策略实现多种烯烃双官能化的重氮化合物的新反应。重氮化合物在光催化剂或铁催化剂的作用下通过 PCET 过程转化为碳自由基。碳自由基选择性地添加到不同的烯烃中，提供新的碳自由基物种，然后通过硫醇辅助的氢原子转移 (HAT) 通过加氢烷基化形成产物，或通过铁催化循环形成叠氮烷基化产物。这两个过程是高度互补的，在温和的反应条件下进行，并表现出高度的官能团耐受性。此外，这两种转化都在克级规模上成功进行，并且可以使用市售试剂轻松制备各种 γ-氨基酯、γ-氨基醇和复杂的螺内酰胺。机理研究揭示了将这两个过程联系起来的合理途径，并解释

  作者：Stefan P. A. Hinkes、Christian D. P. Klein

  日期：2019.5.3

  Boronic acids are an increasingly important compound class for many applications, including C–C bond formation reactions, medicinal chemistry, and diagnostics. The deprotection of boronic ester intermediates is frequently a problematic and inefficient step in boronic acid syntheses. We describe an approach that highly facilitates this transformation by leveraging the volatility of methylboronic acid and

  C–B bond of the γ-dimethylamino tertiary boronic esters can be transformed into a variety of functional groups (C–OH, C–vinyl, C–H, C–BF3), thus giving a diverse selection of 3-aryl-1-aminopropanes, which represent a privileged motif among drug molecules. In situ generated 2-phenyl-azetidinium ylides react with boronic esters to form acyclic γ-dimethylamino tertiary boronic esters. The transformation
