Synthese substituierter chiraler [2.2]Paracyclophane und deren Einsatz in asymmetrischen Katalysereaktionen

The element of planar chirality turned out to be of special importance to achieve high enantioselectivities in various asymmetric processes. However, only few planar chiral compounds based on [2.2]paracyclophane were tested as ligands in asymmetric catalytic reactions. In the course of this PhD thesis, disubstituted chiral [2.2]paracyclophanes were synthesized and tested as ligands in asymmetric, catalytic reactions. One of three topics was the synthesis of phosphinyl-oxazolinyl-[2.2]paracyclophanes. For the synthesis of the ortho-substituted [2.2]paracyclophanes the intermediate formation of palladacycles was essential. Different kinds of [2.2]paracyclophane-based oxazolines were synthesized, which were tested as N,O-ligands in the asymmetric phenyl-transfer to aldehydes. Furthermore, pseudo-geminally substituted [2.2]paracyclophanes were applied in various asymmetric catalytic reactions.
