1,3-Dienes are readily available feedstocks that are widely used in the laboratory and industry. However, the potential of converting 1,3-dienes into value-added products, especially chiral products, has not yet been fully exploited. By synergetic photoredox/copper catalysis, we achieve the first visible-light-induced, enantioselective carbocyanation of 1,3-dienes by using carboxylic acid derivatives

phosphates reacted regio- and stereo-selectively with a variety of organocopper reagents to give γ-coupling products, (Z)-predominant alk-2-enenitriles. The methodology was applied to the synthesis of (±)-nuciferal, (±)-(E)- and -(Z)-nuciferol, and (±)-manicone.
