Sulfonate bearing chiral bidentate N-heterocyclic carbene (NHC) complexes promote catalytic enantioselective allylic substitution reactions, which involve the use of alkyl- or aryl-substituted vinylaluminum reagents and afford 1,4-dienes containing a quaternary carbon stereogenic center at their C-3 site.
