(Matrix presented) A new ligand for Cu-catalyzed enantioselective additions of dialkylzincs to cyclic enones has been developed. In addition to providing good to excellent enantioselectivities with a range of cyclic enones and dialkylzincs, the ligand has several notworthy features: it can be readily prepared in just two steps, is an air-stable crystalline solid, and provides optimal performance at ambient temperature.
C3-Symmetric tripodal tetra-amines - preparation from chiral amino alcohols via aziridines

Enantiopure N-sulfonylaziridines, conveniently obtained from readily available enantiopure amino alcohols, undergo smooth ring opening reactions using ammonia as a nucleophile to yield tripodal tetradentate C3-symmetric amines. N-alkylation and
