A new protocol for the controlled reduction of nitriles to aldehydes was developed using a combination of sodium hydride and zinc chloride. The iminyl zinc intermediates derived from aromatic nitriles could be further functionalized with allylmetal nucleophiles to afford homoallylamines. As the method allows the reduction of various aliphatic and aromatic nitriles with a concise procedure under milder reaction conditions and exhibits wide functional group compatibility, it is well suited for use in various opportunities in chemical synthesis.

氢化钠和氯化锌控制的腈还原

使用氢化钠和氯化锌的组合，开发了一种控制腈还原为醛的新方案。衍生自芳族腈的亚胺基锌中间体可以用烯丙基金属亲核试剂进一步官能化以提供高烯丙基胺。由于该方法可以在较温和的反应条件下以简明的方法还原各种脂族和芳族腈，并且具有广泛的官能团相容性，因此非常适合用于化学合成中的各种机会。
