Design of a Combinational Magnesium Catalyst for the Stereocontrolled Cross Reaction of Enones

The first stereocontrolled cross reaction of enones has been realized. A novel combinational magnesium catalyst was designed to address the enantioselectivity problem between reaction partners with an intermolecular symmetric structure and bearing identical functional groups. This new catalytic strategy was proven to be effective to introduce high levels of enantioselectivity in the cross reaction of enones.
