Control of diastereoselectivity in tandem asymmetric reactions generating nonadjacent stereocenters with bifunctional catalysis by cinchona alkaloids

We report the manipulation of hydrogen-bonding-based cooperative catalysis to control the diastereoselectivity for a tandem asymmetric reaction creating two nonadjacent stereocenters. This ability to control both the enantioselectivity and diastereoselect
