The present invention provides processes for the production of chiral compounds in a stereoisomeric excess. The present processes involve reacting a hydrometallated alkene compound with a compound comprising a conjugated -bond system under conditions such that the compounds undergo an asymmetric 1,4- or 1,6-conjugate addition reaction, generating a chiral compound in a stereoisomeric excess. The reaction is performed in the presence of a metal catalyst, which catalyst preferably comprises a non-racemic chiral ligand.

Copper catalysis allows alkyl zirconium species, generated in situ from alkenes, to undergo conjugate addition reactions. A hydrometallation-catalytic asymmetric 1,4-addition was used to synthesize either enantiomer of a natural product in one step from commercially available materials. Hydrometallation-addition sequences applied to steroids containing a cross-conjugated dienone or 1,6-acceptor give highly functionalized products.
