A series of α,β-divinyl tetrahydropyrroles, synthesized by asymmetric allylic C−H bond activation/conjugated diene addition reaction of ene-2-dienes, were found to be very efficient chiral chain diene ligands in the rhodium-catalyzedconjugatedaddition of organoboronic acids to various α,β-unsaturated compounds, achieving the desired chiral adducts with good to excellent yields and ee values.
