  Enantioselective Catalytic Addition of HCN to Ketoimines. Catalytic Synthesis of Quaternary Amino Acids

  摘要：

  Highly enantioselective addition of HCN to ketoimines has been achieved for the first time using readily accessible and recyclable Schiff base catalysts. Essentially quantitative isolated yield and enantioselectivity of up to 95% ee was obtained. Furthermore, some of the Strecker adducts could be recrystallized in high recovery, yielding optically pure materials. Conversion of the alpha-aminonitrile adducts to the corresponding alpha-quaternary alpha-amino acids was effected in high yield by a formylation/hydrolysis sequence.

• Solvent-Free Synthesis of Racemic α-Aminonitriles

  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。

  Aryl imines formed from aldehydes and amines undergo smoothly in situ nucleophilic addition with trimethylsilyl cyanide (TMSCN) in the presence of catalytic amount of hydrated rhodium(III) iodide to afford the corresponding α-aminonitriles in excellent yield. The low catalytic loading (2 mol %), mild experimental conditions, and short reaction time (mostly within 13 min) represent the key features

  Trimethylsilyl cyanide was found to react with Schiff bases and oximes in the presence of a catalytic amount of Lewis acids to afford N-trimethylsilyl-α-aminonitriles and N-trimethylsilyloxy-α-aminonitriles in excellent yields, which were easily hydrolyzed to the corresponding α-aminonitriles and α-hydroxyaminonitriles.

  The synthetic utility of N-heterocyclic carbenes was demonstrated by the trialkylsilylcyanation of aldehydes, ketones and imines. In the presence of a catalytic amount of 3a, the reactions with Me3SiCN proceeded smoothly to give the corresponding cyanohydrin trimethylsilyl ethers or amino nitrile derivatives in good to excellent yields.

  Strecker reaction for the synthesis of α‐aminonitriles was developed. The milling of aldehydes, amines, and potassium cyanide in the presence of SiO2 gave the corresponding α‐aminonitriles in good to high yields. The high efficiency of the mechanochemical Strecker‐type multicomponent reaction allowed the one‐pot synthesis of tetrahydroisoquinolines after a subsequent internal N‐alkylation reaction.

  开发了用于合成α-氨基腈的Strecker反应的机械化学形式。在SiO 2的存在下对醛，胺和氰化钾进行研磨，可以以高至高收率得到相应的α-氨基腈。机械化学的Strecker型多组分反应的高效率使得在随后的内部N烷基化反应后可以一锅合成四氢异喹啉。
