Pd-catalyzed asymmetric C–Hbondactivation for the synthesis of P-stereogenic dibenzophospholes was efficiently achieved via two types of catalytic systems. Chiral phosphoric amides/acids as ligands provided the products with up to 5:95 er, and (R)-segphos as ligand resulted in enantioselectivities of up to 98:2.
