Axially chiral nitriles are common motifs in organic photoelectric materials, biological compounds, and agrochemicals. Unfortunately, the limited synthetic approaches to axially have impeded their availability. Herein, we report first nickel-catalyzed desymmetric allylic cyanation of biaryl alcohols for synthesis nitrile structures high yields with excellent enantioselectivities (up 90 % yield >99 ee). This process enables a diverse range bearing β,γ-unsaturated alcohol moieties. Leveraging cyano groups as versatile functionalization handles allow further derivatization these frameworks. Density functional theory (DFT) calculations suggest that both steric electronic interactions play crucial roles determining enantioselectivity this transformation. Moreover, mild facile protocol is also applicable gram-scale preparation nitriles.
