Synthesis of Quaternary Carbon Stereogenic Centers Through Enantioselective Cu‐Catalyzed Allylic Substitutions with Vinylaluminum Reagents.

Catalytic enantioselective allylic substitution reactions using alkyl- and aryl-substituted vinylaluminum reagents afford 1,4-dienes containing a quaternary carbon stereogenic center at C-3, also by addition of a vinyl unit.
