structure, the 5-membered chiral biaryl heterocyclic scaffold represents a departure from 6-membered P,N-ligands that facilitates tuning and enables ligand evolution to address issues of selectivity and reactivity. In this vein, the Cu-catalyzedenantioselective conjugate alkynylation of Meldrum's acid acceptors is reported using Me-StackPhos. Enabled by this new ligand, the reaction tolerates a wide range
