Separation of atropisomers by chiral liquid chromatography and thermodynamic analysis of separation mechanism☆
In the pharmaceutical industry, the analysis of atropisomers is of considerable interest from a scientific and regulatory perspective. The compound of interest contains two stereogenic axes due to the hindered rotation around the single bonds connecting the aryl groups, which results in four potential configurational isomers (atropisomers). The separation of the four atropisomers is achieved on...
متن کاملEnantiomeric signatures of chiral polychlorinated biphenyl atropisomers in livers of harbour porpoises (Phocoena phocoena) from the southern North Sea.
The enantiomeric composition of polychlorinated biphenyl (PCB) atropisomers, including PCB 95, PCB 149 and PCB 132, was measured in 11 livers of harbour porpoises (Phocoena phocoena) from the southern North Sea. Non-racemic enantiomeric ratios (ERs) were found in some samples. The value of ERs in three of the four juvenile porpoises was equal or almost equal to one, while the ERs in all adults ...
متن کاملThe isolation and photochemistry of individual atropisomers of photochromic diarylethenes.
All three atropisomers of photochromic diarylethenes were isolated for the first time and the stereospecific photochemical switching process studied by UV-vis and CD spectroscopy.

متن کاملA switchable self-assembling and disassembling chiral system based on a porphyrin-substituted phenylalanine–phenylalanine motif
Artificial light-harvesting systems have until now not been able to self-assemble into structures with a large photon capture cross-section that upon a stimulus reversibly can switch into an inactive state. Here we describe a simple and robust FLFL-dipeptide construct to which a meso-tetraphenylporphyrin has been appended and which self-assembles to fibrils, platelets or nanospheres depending o...
