Abstract
By using synergetic photoredox/copper catalysis, a visible-light-induced, enantioselective carbocyanation of 1,3-dienes with carboxylic acid derivatives and trimethylsilyl cyanide is achieved under mild and neutral conditions. A diverse range of chiral allyl cyanides is produced in generally good efficiency and with high enantioselectivity from bench-stable and user-safe chemicals.
