Use of visible-light is regarded as attractive and advantageous method for development of selective and efficient synthetic methodology. To approach enantioselective visible-light induced photoredox catalysis, various synergistic catalysis have been developed recently. For example, transition-metal based photoredox catalyst coupled with chiral amine, Brønsted acid organocatalyst, and Lewis acid catalyst. In this research, we developed enantioselective radical addition to various aldehyde compounds in the presence of chiral Lewis acid catalyst and transition-metal based photoredox catalyst. Using this methodology, we synthesized highly optically active β-amino alcohol derivatives with good yields (up to 99%) and high enantioselectivities (up to 98% ee).
