L-Proline rubidium salt catalyzes the asymmetric Michael addition of nitroalkanes to enones and an enal. (R)-Adducts were obtained from cyclic (Z)-enones and (S)-adducts from acyclic (E)-enones. Bu3SnH treatment of the products replaced the nitro group with hydrogen atom. The overall transformation allows the asymmetric alkylation of enones at the β-carbon atom.
