Using chiral phosphoramidite ligand (S,R,R)-L1 in the conjugate addition to acyclic nitroalkenes for the first time, we obtained enantioselectivities up to 98%. The use of acyclic substrates with different dialkylzinc reagents provides a catalytic enantioselective route to (functionalized) β2-amino aldehydes, acids, and alcohols.
