Twenty new chiral (aminoalkyl)phosphane ligands have been prepared from four enantiomerically pure advanced chiral compounds. We describe their use for asymmetric hydrogen-transfer reduction of three prochiral ketones. Enantioselectivities up to 90% were obtained. We investigated the influence on the enantioselectivity of each part of these new (aminoalkyl)phosphane ligands. (© Wiley-VCH Verlag GmbH
已经从四种对映体纯的高级手性化合物制备了 20 种新的手性(氨基烷基)膦配体。我们描述了它们在三个前手性酮的不对称氢转移还原中的用途。获得了高达 90% 的对映选择性。我们研究了这些新(氨基烷基)膦配体的每一部分对对映选择性的影响。(© Wiley-VCH Verlag GmbH & Co. KGaA, 69451 Weinheim, Germany, 2003)
