In the presence of visible-lightphotoredox and chiral phosphate catalysts, a novel asymmetric Friedel–Crafts reaction of indoles and readily accessible α-amino acid derived redox-active esters is established to afford enantioenriched 1-indolyl-1-alkylamine derivatives in moderate to high yields and with high levels of enantioselectivities. This method not only shows a mild and efficient alternative
