Unprotected alicyclic amines undergo α-C–H bond phosphonylation via a two-stage one-pot process involving the oxidation of amine-derived lithium amides with simple ketone oxidants, generating transient imines which are then captured with phosphites or phosphine oxides. Amines with an existing α-substituent undergo regioselective α′-phosphonylation. Amine α-arylation and α′-phosphonylation can be combined
未受保护的脂环胺通过两阶段一锅法进行 α-C-H 键膦酰化,涉及用简单的酮氧化剂氧化胺衍生的氨基锂,产生瞬时亚胺,然后用亚磷酸酯或氧化膦捕获。具有现有 α-取代基的胺会发生区域选择性 α'-膦酰化。胺 α-芳基化和 α'-膦酰化可以组合起来,在一次操作中生成双官能化产物。
