nickel-catalyzed borylative coupling of 1,3-dienes with aldehydes, providing an efficient route to highly valuable homoallylic alcohols in a single step. The reaction involves the 1,4-carboboration of dienes, leading to the formation of C–C and C–B bonds accompanied by the construction of two continuous stereogenic centers. Enabled by a chiral spiro phosphine-oxazoline nickel complex, this transformation yields
我们提出了第一个对映选择性镍催化的 1,3-二烯与醛的硼化偶联,为一步生产高价值的高烯丙醇提供了有效的途径。该反应涉及二烯的 1,4-碳硼化,导致 C-C 和 C-B 键的形成,同时构建两个连续的立体中心。通过手性螺环膦-恶唑啉镍络合物,该转化产生具有优异的非对映选择性、E选择性和对映选择性的产物。反应的非对映选择性可以通过使用( Z )-1,3-二烯或( E )-1,3-二烯来控制。
