摘要：

The axial chirality of tropos gold-biphep (biphep=bis (phosphanyl)biphenyl) complexes, which is controlled by a chiral anion such as (S)-2 (=X *-), is imprinted and memorized even after the dissociation of chiral anion. An enantiopure complex thus obtained efficiently function as an atropos asymmetric catalyst in an intramolecular hydroamination. © 2009 Wiley-VCH Verlag GmbH & Co. KGaA.
