Abstract

This perspective is focused on the main parameters determining the results of crystallization of enantiomers or enantiomeric mixtures. It was shown that the ratio of supramolecular and helical associations depends on the eutectic composition of the corresponding enantiomeric mixture. The M and P ratios together with the self-disproportionation (SDE) of enantiomers define the reaction of the racemic compound with the resolving agent. Eventually, each chiral molecule reacts with at least two conformers with different degrees of M and P helicity. The combined effect of the configuration, charge distribution, constituent atoms, bonds, flexibility, and asymmetry of the molecules influencing their behavior was also summarized.
Keywords: chiral molecules; enantiomeric separation; self-disproportionation of enantiomers; supramolecular associations; helical structure; eutectic composition chiral molecules; enantiomeric separation; self-disproportionation of enantiomers; supramolecular associations; helical structure; eutectic composition
