Atropisomerism in a polyglutamate-based thermoresponsive alignment medium

Dominic S. Schirra

Philipp Götz

et al.

Abstract: Structure elucidation via residual dipolar couplings (RDCs) relies on alignment media. We report on lyotropic liquid crystals (LLCs) of poly-γ-p-biphenyl(2’-methoxy-2-methyl)methyl-L-glutamate (PBPM3LG). Temperature dependent atropisomerism within the biphenyl group enables the...

This book chapter covers relevant articles published in peer-reviewed journals in 2022 in the field of NMR spectroscopy of small molecules in solution. Articles that appeared in 2022 as accepted online versions but not published in the journal’s issue are not included. The chapter is structured into six sections: NMR pulse sequence development, structural determination in oriented media, mixture analysis, quantitative NMR, NMR chiral recognition methodologies and machine learning in NMR. Even though many articles could fit in more than one section, since most of the topics are intimately related. A short and concise introduction of each section is given, but the reader should not expect a fully detailed review, nor a simple, non-detailed listing of articles. Instead, the reader shall find distilled information with the key points, the main goals, and a personal interpretation of the success of the reported articles.

This chapter points out the main challenges of using anisotropic NMR parameters for organic structure elucidation and also where differences to biomolecular applications lie. The challenges include the necessity of determining configurations and conformations at the same time, the diverse and extended spin-systems present in organic compounds and the necessity of using organic solvents. The chapter aims at providing an overview of the most recent solutions to these challenges and which opportunities there are if one uses anisotropic NMR parameters for structure elucidation of organic compounds.
