Reaction conditions: 1d (0.05 mmol), 2a (3 equiv), 3a (4 equiv), Pd(OAc)2 (10 mol%), chiral ligand (20 mol%), BQ (20 mol%), NaF (2 equiv), HFIP/THF/DMF (2:2:1, 0.1 mL), 45 °C, O2 (1 atm), 5 d. Percentages refer to 1H NMR yields with CH2Br2 as internal standard. The enantioselectivity was determined by SFC analysis.
