α‐Aminonitriles as key intermediates for the preparation of α‐amino acid derivatives, amides, diamines, peptides, proteins and heterocycles were synthesized through methylarene oxidation in the Strecker reaction using a unique combination of KI/ZnFe2O4 as the best catalyst and aqueous tert‐butylhydroperoxide as oxidant. A wide range of amines and methylarenes were converted to the corresponding products
α-氨基腈是制备α-氨基酸衍生物,酰胺,二胺,肽,蛋白质和杂环的关键中间体,是在Strecker反应中通过甲基芳烃氧化合成的,采用独特的KI / ZnFe 2 O 4作为最佳催化剂,叔丁基过氧化氢水溶液作氧化剂。多种胺和甲基芳烃被转化为相应的产物。操作简便,反应时间短和催化剂的可回收性是该方案的优势。

The Strecker reaction is the most widely applied three-component reaction. Although highly useful for the preparation of α-amino nitriles, α-amino acids, hydantoins and numerous related compounds, the need for the application of toxic sources of HCN limits its application in both academic and industrial settings. Here, we present a facile protocol for Strecker reactions using a mixture of potassium
Dehydroascorbic acid (DHAA) capped magnetite nanoparticles as an efficient magnetic organocatalyst for the one-pot synthesis of α-aminonitriles and α-aminophosphonates
A dehydroascorbic acid capped magnetite (DHAA-Fe3O4) catalyst is prepared and used for the one-pot synthesis of alpha-aminonitriles and alpha-aminophosphonates. Different derivatives of these compounds are synthesized in good yields. (C) 2013 Elsevier Ltd. All rights reserved.
