Copper-catalyzed directed decarboxylative amination of nonactivated aliphatic carboxylic acids is described. This intramolecular C-N bond formation reaction provides efficient access to the synthesis of pyrrolidine and piperidine derivatives as well as the modification of complex natural products. Moreover, this reaction presents excellent site-selectivity in the C-N bond formation step through the
描述了铜催化的非活化脂肪族羧酸的定向脱羧胺化。这种分子内 CN 键形成反应为合成吡咯烷和哌啶衍生物以及复杂天然产物的修饰提供了有效途径。此外,该反应通过使用导向基团在 CN 键形成步骤中表现出优异的位点选择性。我们的工作可以被认为是朝着可控自由基脱羧碳-杂原子交叉偶联迈出的一大步。
