selective synthesis of primary aminesfrom easily available precursors is attractive yet challenging. Herein, we report the rapid synthesis of primary aminesfrom alkenes via metal‐free regioselective hydroamination at room temperature. Ammonium carbonate was used as ammonia surrogate for the first time, allowing for efficient conversion of terminal and internal alkenes into linear, α‐branched, and α‐tertiary

A quinone-mediated general synthetic platform for the construction of primary α-tertiary amines from abundant primary α-branched amine starting materials is described. This procedure pivots on the efficient in situ generation of reactive ketimine intermediates and subsequent reaction with carbon-centered nucleophiles such as organomagnesium and organolithium reagents, and TMSCN, creating quaternary
描述了一种醌介导的通用合成平台,用于从丰富的伯 α-支化胺起始材料构建伯 α-叔胺。该过程的重点是有效地原位生成反应性酮亚胺中间体,并随后与碳中心亲核试剂(例如有机镁和有机锂试剂以及 TMSCN)反应,产生四元中心。此外,扩展到反极性光氧化还原催化可以通过亲核α-氨基自由基中间体与亲电子试剂发生反应。这种高效、广泛适用且可扩展的胺对胺合成平台已成功应用于库和 API 合成以及药物分子的功能化。
