A one-pot, enantioselective synthesis of N-aryl propargylic amines, using alkynylation reagents obtained from dimethylzinc and terminal acetylenes in combination with various aldehydes and o-methoxyaniline as starting materials, has been developed. Enantiopure beta-amino alcohols derivedfromnorephedrine were used as non-covalent chiral auxiliaries, both in stoichiometric or substoichiometric amount
