Significance

The authors report efficient and ­selective bifunctional chiral amido ruthenium and iridium complexes for the asymmetric conjugate addition of α-substituted cyanoacetates to acetylenic esters. Furthermore, spectroscopic and computational studies provide insight into catalytically relevant intermediates and transitions states.
