Catalytic asymmetric conjugate addition reactions are very important tools for the assembly of chiral compounds and Meldrum’s acid derivatives are excellent acceptors for such transformations. Facile diversification of β–alkynyl adducts makes them highly useful targets and a new synthetic method using StackPhos, an imidazole–based atropisomeric P,N–ligand has been developed. Employing a ligand modification strategy, this transformation was achieved with a broad substrate scope and excellent enantioselectivity. Recent results using modified ligands will be presented, as well as the application of the method.
