Anexo-lent catalyst: An N,O-ligand/Cu(OAc)2 derived chiral complex is an excellent catalyst for inducing asymmetry in the catalytic enantioselective 1,3-dipolar cycloadditions of azomethine ylides with various alkylidene malonates. A series of highly functionalized exo-pyrrolidines were obtained in excellent yields (80–99 %) and enantioselectivities (91–99 % ee; see scheme; M.S.: molecular sieve).
