Previously it was demonstrated that maleoylcobalt and phthaloylcobalt complexes react with alkynes and produce substituted quinones after oxidative decomplexation. Herein is reported a study of the deprotonation of 3,4- dimethylmaleoylcobalt complexes leading to a reactive dienolate that on treatment with electrophiles provides new cobalt complexes functionalized at either the γ- or α-position of the

proline-derived catalyst, providing access to the desired adducts in up to 95% yield, 1:19 syn/anti and 98% e.e. Moreover, even sterically bulky aldehydes and substituted cyclohexanones were well tolerated. DFT calculations and control experiments indicated that several hydrogen bonding interactions between the aldehyde and the enamine intermediate are responsible for the stereoselective chiral induction process
