摘要
A synthetic route to racemic and enantiopure planar chiral [2.2]paracyclophanes with amide groups was developed to combine the well-established reactivity of amides as N,O-chelating ligands in hydroamination reactions with the planar chirality of the [2.2]paracyclophane backbone. A mono- as well as a tethered bis(amide) were synthesized and investigated as ligands for titanium and zirconium. Hydroamination reactivity studies showed their ability to translate their planar chirality into central chirality in the product.
