Kurzbeschreibung (Abstract)

Residual dipolar couplings (RDCs) offer additional information for structure elucidation by NMR spectroscopy. They are measured in anisotropic media, such as lyotropic liquid crystalline phases of polypeptides. Today, some suitable polypeptides are known. Nevertheless, structural influences of these polypeptides on the alignment properties are not really understood. Thus, which influence a chiral side chain has on enantiodiscrimination and whether we can improve the enantiodifferentiation significantly by adding an additional chiral center in the side chain are questions of interest. Therefore, new diastereomeric polypeptide‐based alignment media with an additional chiral center in the side chain derived from perillyl alcohol were synthesized and their properties were investigated (secondary structure, liquid crystallinity, etc.). The enantiomers of isopinocampheol and β‐pinene were used as model analytes for the study of enantiodiscrimination. Additionally, the usage of ¹H–¹H‐RDCs to improve the alignment tensor quality is demonstrated.

Influences on enantiodifferentiation: The influence of an additional chiral center in the side chain of a polypeptide-based alignment medium was investigated. Therefore, new diastereomeric alignment media were synthesized and the enantiomers of IPC and β-pinene were used as analytes. The results are unexpected. Furthermore, ¹H–¹H‐RDCs (residual dipolar couplings) are used to improve the quality of alignment tensors.
