Abstract

The [2.2]paracyclophane-derived oxazole-pyrimidine ligands with planar chirality (PYMCOX) were designed, synthesized and successfully applied in nickel-catalyzed asymmetric 1,2-reduction of α,β-unsaturated ketones, affording the chiral allylic alcohols with up to 99% yield and 99% ee. Meanwhile, this reduction reaction could be conducted on gram-scale without loss of activity and enantioselectivity, and the chiral ligand could be conveniently recovered with high yield.
