The development of chiral ligands with privileged scaffolds plays an important role in transition-metal-catalyzed asymmetric reactions. Herein we present anthracene-photodimer-derived chiral monophosphine ligand 1, which features dual chirality and a rigid scaffold. This ligand exhibits remarkable efficiency in Pd-catalyzed desymmetric intermolecular C–N coupling under mild conditions with excellent
具有特权支架的手性配体的开发在过渡金属催化的不对称反应中起着重要作用。在此,我们提出了蒽-光二聚体衍生的手性单膦配体1,其具有双重手性和刚性支架。该配体在温和条件下在 Pd 催化的去对称分子间 C-N 偶联中表现出显着的效率,具有优异的化学和对映选择性。
