A helping hand: A series of bis(oxazoline) ligands, which contain pendant C2-symmetry-breaking groups, for the Cu-catalyzed asymmetric cyclopropanation of 1,2-disubstituted alkenes has been developed. Under mild reaction conditions, both cis- and trans-1,2-substituted alkenes can be converted into the corresponding 1,2,3-trisubstituted cyclopropanes with high levels of diastereo- and enantioselectivity (see scheme).
