Enantioenriched, substituted tetrahydrofuran skeletons extensively occur in natural products, bioactive targets, and organic frameworks. The rapid and diverse synthesis of these tetrahydrofuran molecules is highly desired yet challenging. Herein, we present a practical synthetic strategy for asymmetric allylic C–H bond functionalization of oxyheterocyclic alkenes by making use of the synergistic catalysis of achiral Pd complex and chiral N, N ′-dioxide-Ni(II) catalyst. Notably, the chemodivergent synthesis of allylic C–H alkylated products and hydroalkylated products was readily achieved in good outcomes via the regulation of solvents. Furthermore, the post-transformation of these functionalized 2,5-dihydrofurans provides an innovative synthetic route to access tetrahydrofuran skeleton compounds containing multiple stereocenters.
