Reaction conditions: oxime carbonate 1a (0.2 mmol), unactivated olefins (0.4 mmol), Michael acceptors (0.4 mmol), and thioxanthone (5.0 mol %) in EtOAc (0.1 M), irradiation with 18 W blue LEDs (λmax = 405 nm) under an argon atmosphere at room temperature for 12 h.
Isolated yields are given. The d.r. values were determined by 1H NMR analysis.
