preparation of optically active propargylamines is described. The alkynylation of aromatic, heteroaromatic, aliphatic and α,β-unsaturated N-(diphenylphosphinoyl)imines was investigated by using diethylzinc and a proline-derived β-amino alcohol. N-(Diphenylphosphinoyl)-protected propargylic amines can be synthesized in high yields and with good to excellent enantioselectivities. (© Wiley-VCH Verlag GmbH
