catalysts reported before were unsuccessful in this enantioselective radical C−N bond formation. The surprising preference for rhodium over iridium is attributed to much faster ligand‐exchange kinetics of the rhodium complexes involved in the catalytic cycle, which is crucial to keep pace with the highly reactive and thus short‐lived nitrogen‐centered radical intermediate.

Chiral-at-metal Rh(III) complexes catalyzed highly efficient enantioselectiveMannichreaction of 2-acyl imidazoles with 1,3,5-triazinanes is developed, affording the corresponding adducts in 81-99% yields with up to >99% enantioselectivities. This protocol performs with 0.1 mol % of Rh(III) complex on gram scale without loss in enantioselectivity.
An enantioselective, catalytic trichloromethylation of 2-acyl imidazoles and 2-acylpyridines is reported. Several products are formed with enantiomeric excess of ≥99%. In this system, a chiral iridium complex serves a dual function, as a catalytically active chiral Lewis acid and simultaneously as a precursor for an in situ assembled visible-light-triggered photoredox catalyst.
A nickel(II)-catalyzed asymmetric direct vinylogous Michael addition of γ-alkyl monosubstituted α,β-unsaturated butyrolactams to α,β-unsaturated carbonyl compounds has been disclosed, affording γ,γ-dialkyl substituted butyrolactams in good yields and satisfactory enantioselectivities. A tandem catalyticasymmetric vinylogous Michael addition/intramolecular Michael addition has also been developed based
