Catalytic asymmetric1,3-dipolarcycloaddition of azomethineylides to ethynyl ketones catalyzed by the Cu(OAc)2/FOXAP (ferrocenyl oxazolinylphosphine) complex was developed, affording 2,5-dihydropyrrole derivatives in good to excellent yields (up to 99%) and excellent levels of enantioselectivities (up to 98% ee). This highly efficient chiral N,P-ligand/Cu(OAc)2 catalytic system was also applicable
