Significance
Extending the scope of their C 1-symmetric amino sulfoximine/copper system, the authors report a highly enantio- and diastereoselective vinylogous Mukaiyama aldol (VMAR) reaction of O-silylated dienolates and pyruvates. This catalyst tolerates a wide range of structurally and electronically diverse pyruvate electrophiles to afford products containing two adjacent stereocenters in excellent yields and selectivities.
