Secondary alicyclic amines are converted to α-aminonitriles via addition of TMSCN to their corresponding imines, intermediates that are produced in situ via the oxidation of amine-derived lithium amides with simple ketone oxidants. Amines with an existing α-substituent undergo regioselective α′-cyanation even if the C–H bonds at that site are less activated. Amine α-arylation can be combined with α′-cyanation
通过将 TMSCN 添加到相应的亚胺上,脂环族仲胺转化为 α-氨基腈,亚胺是通过用简单的酮氧化剂氧化胺衍生的氨基锂而原位产生的中间体。具有现有 α-取代基的胺会发生区域选择性 α'-氰化,即使该位点的 C-H 键活性较低。胺α-芳基化可以与α'-氰化结合,在一次操作中生成双官能化产物。
