The preparation of N-containing α,β-unsaturated carboxylate derivatives from α-silylamine and Baylis-Hillman adducts under visible light irradiation was reported. The formation of α-aminoalkyl radical is regioselective compared with the previous reports. The reaction was successfully performed without additional additives under mild conditions.
