to more effectively understand their behaviour during catalysis. These ligands and some previously reported P-stereogenic ligands were tested in the rhodium catalysed asymmetric addition of phenyl boronic acid to napthaldehyde. These studies in asymmetric catalysis were used to compare the chiral induction of ligands that combine both axial and central chirality with ligands lacking P-stereogenicity
合成报道新颖的P -stereogenic联萘取代的单膦经由使用与所述硼烷保护的非对映体产物的分离镍偶联反应的短五步合成。对这些配体与许多众所周知的金属前体进行了广泛的配位研究,以更有效地了解其在催化过程中的行为。 这些配体和一些以前报道的P-立体异构体配体在铑催化的萘基苯硼酸的不对称加成中进行了测试。这些在不对称催化中的研究用于比较将轴向和中心手性与缺乏P-立体异构性的配体相结合的配体的手性诱导。
