Chiral tridentate P,N,N ligands have been demonstrated to be highly efficient for the coppercatalyzed enantioselective propargylic amination of propargylic acetates with both primary and secondary amines as nucleophiles, affording the corresponding propar

(Chemical Equation Presented) A proper copper catalyst with a chiral pyridine-2,6-bisoxazoline (pybox) ligand was used to convert a variety of propargylic acetates with aromatic side chains (R = Ar) into their amine counterparts in high yield and with good selectivity (up to 88% ee). The resulting chiral propargylic amines can be elaborated further into P,N ligands (see scheme; DIPEA = diisopropylethylamine).
