heterocycles is a privileged skeleton due to their outstanding catalytic properties and bioactivities. However, their enantioselective synthesis is still underdeveloped. Here we demonstrate the use of easily accessible racemic H–P(O) compounds as starting materials and commercial chiral N1, N2‐dimethyl‐1,2‐diphenylethane‐1,2‐diamine ligand in combination with Cu(I) catalysts to enable an attractive dynamic
