designed and accomplished for the synthesis of α‐aminonitriles with alcohol as the alkylation reagent. The strategy is environmentally friendly, scalable, and compatible with a wide range of functional groups, encompassing aromatic primary amines, secondary amines, and even alkylamine. Utilizing the merits of electro‐organic synthesis, it can be readily magnified from milligram to gram scale by simply adjusting
α-氨基腈是药物化学中用途广泛且有价值的中间体。到目前为止,Strecker 反应仍然是合成这些化合物的最有效的工具。然而,它仅适用于醛/亚胺体系,并且通常需要金属催化剂和外部添加剂。在此,设计并实现了一种电化学驱动的氧化Strecker反应策略,用于以醇作为烷基化试剂合成α-氨基腈。该策略是环境友好的、可扩展的,并且与多种官能团兼容,包括芳香伯胺、仲胺,甚至烷基胺。利用有机电合成的优点,只需调整电化学参数,就可以轻松地将其从毫克级放大到克级。强调的是,它证明了燃料电池中广泛存在的独特中间体 CH2*OH 参与了该反应。
