The use of β‐ketosulfoxides as nucleophiles in reactions with α,β‐unsaturated aldehydes catalyzed by proline derivatives allows complete control of configuration at the two chiral centers that are created during 1,4‐addition reactions. The sulfinyl group can be used to create additional chiral centers in the resulting compounds and then removed while preserving the chirality of the carbon joined to
