  Redox-Neutral α-Cyanation of Amines

  摘要：

  alpha-Aminonitriles inaccessible by traditional Strecker chemistry are obtained in redox-neutral fashion by direct amine alpha-cyanation/N-alkylation or alternatively, alpha-aminonitrile isomerization. These unprecedented transformations are catalyzed by simple carboxylic acids.

  A modular and waste‐free strategy for constructing N‐substituted cyclic amines via decarboxylative N‐alkylation of α‐amino acids employing ruthenium‐ and iron‐based catalysts is presented. The reported method allows the synthesis of a wide range of five‐ and six‐membered N‐alkylated heterocycles in moderate‐to‐excellent yields starting from predominantly proline and a broad range of benzyl alcohols

  提出了一种采用钌和铁基催化剂通过α-氨基酸的脱羧N-烷基化N-取代环胺来构建N-取代环胺的模块化，无浪费的策略。报道的方法允许以中等至优异的产率合成大量的五元和六元N烷基化杂环，主要从脯氨酸和各种苯甲醇以及伯和仲脂肪醇开始。还显示了使用胡椒酸构建哌啶衍生物以及一锅法合成α-氨基腈的实例。

  alpha-Amino acids react with aldehydes in the presence of a cyanide source to form alpha-amino nitriles in what can be considered a decarboxylative variant of the classical Strecker reaction. This unprecedented transformation does not require the use of a metal catalyst and provides facile access to valuable alpha-amino nitrites that are inaccessible by traditional Strecker chemistry.
