A copper‐catalyzed three‐component coupling of allenes, bis(pinacolato)diboron, and imines allows regio‐, chemo‐, and diastereoselective assembly of branched α,β‐substituted‐γ‐boryl homoallylic amines, that is, products bearing versatile amino, alkenyl, and borane functionality. Alternatively, convenient oxidative workup allows access to α‐substituted‐β‐amino ketones. A computational study has been
铜催化的三烯,双(频哪醇)双硼硼烷和亚胺的三组分偶联使得支链的α,β-取代的-γ-硼基均烯丙基胺的区域,化学和非对映选择性组装成为可能,即带有通用氨基的产物,烯基和硼烷官能团。另外,方便的氧化后处理可以使用α-取代的-β-氨基酮。计算研究已被用来探究交叉耦合的立体化学过程。
