Synthesis and application of chiral phosphorous triamide ligands
… and application of novel chiral monodentate phosphorous triamide (PTA) ligands is presented. First, a small library of chiral PTAs based on three different chiral diamine backbones has been prepared through a convenient modular synthetic approach. The study significantly increases the …

Synthese neuer QUINAPHOS-Derivate und deren Einsatz in der asymmetrischen Katalyse
In the present thesis the synthesis of new QUINAPHOS and Dihydro-QUINAPHOS derivatives is described. A major topic of the ligand modification was an enhanced accessiblity of the corresponding diastereomers. In case of derivatives which were 1-naphthyl-substituted in 2-position of the 1,2-dihydro- …
