A Ni-catalyzed enantioselective reductive three-component alkylalkenylation of β,γ-alkenyl ketones with cis-alkenyl iodides and fluoroalkyl iodides in the presence of Mn is reported. By leveraging five-membered nickellacycles stabilized by pendant ketone group and chiral bis(oxazoline) (BiOx) ligand, this three-component protocol allows efficient access to enantioenriched β-alkenyl ketones from simple
报道了在 Mn 存在下,用顺式-烯基碘化物和氟代烷基碘化物对 β,γ-烯基酮进行 Ni 催化的对映选择性还原三组分烷基烯基化反应。通过利用由侧酮基团和手性双(恶唑啉)(BiOx)配体稳定的五元镍环,这种三组分方案允许从简单的起始材料有效地获得对映体富集的 β-烯基酮。Ni催化的β,γ-烯基酮以外的多种电子无偏烯烃的三组分烷基烯基化,能够区域选择性地构建两个C(sp 3 )-C(sp 3 )和C(sp 3 )-(sp 2 )键合二为一还演示了单个操作。
