^aThe reaction was carried out using 2a (0.15 mmol), 3a (0.075 mmol), 2,6-lutidine (0.26 mmol), the corresponding catalyst, and 1 mL of solvent under an Ar atmosphere and blue light irradiation (blue LEDs, 23 W, 450 nm).

^bThe yield was determined by ¹H NMR using nitromethane as the internal standard.
