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
描述了一种用于制备光学活性炔丙胺的新合成方法。通过使用二乙基锌和脯氨酸衍生的 β-氨基醇研究了芳香族、杂芳香族、脂肪族和 α,β-不饱和 N-(二苯基膦酰基)亚胺的炔基化反应。N-(二苯基膦酰基)-保护的炔丙胺可以以高产率合成,并且具有良好到优异的对映选择性。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2009)
