A highly selective copper-catalyzed reductive hydroxymethylation of 1,3-dienes with CO2 provides chiral all-carbon acyclic quaternary stereocenters. A variety of readily available 1,1-disubstituted 1,3-dienes, as well as a 1,3,5-triene, undergo the reaction with high chemo-, regio-, E/Z-, and enantioselectivities and good functional group tolerance.
