A very simple one-step, environmentally friendly procedure for the synthesis of α-aminonitriles from aldehydes and ketones, using trimethylsilyl cyanide in the absence of solvent, is reported. The active catalyst of this three-component (Strecker) reaction was the amine employed in the transformation. In general, aldehydes react more rapidly than ketones and give almost quantitative yields of the corresponding α-aminonitriles in less than fifteen minutes. However, only cyclic ketones afford the corresponding α-aminonitriles in excellent chemical yields under these conditions.
报道了一种非常简单的单步环境友好型方法,通过在无溶剂条件下使用三甲基硅烷腈,从醛和酮合成α-氨基腈。该三组分(Strecker)反应的活性催化剂是用于转化反应的胺。通常情况下,醛比酮反应更快,在不到十五分钟内即可几乎定量地生成相应的α-氨基腈。然而,在这些条件下,只有环状酮能以优异的化学产率生成相应的α-氨基腈。
