We report the mechanism and scope of “preferential enrichment”, which is an unusual symmetry-breaking enantiomeric resolution phenomenon that is initiated by the solvent-assisted solid-to-solid transformation of a metastable polymorphic form into

Two new hydrate cocrystals, (RS)-arginine-fumaric acid-H2O (2) and (S)-arginine-2 fumaric acid-H2O (3), were obtained by the slow evaporation of the saturated aqueous ethanol solution of a 1:1 mixture of S-enriched arginine (33% ee) and fumaric acid

The hydrogen bond motifs in the racemic crystals of the first-generation of chiral organic compounds, which showed a good to excellent preferential enrichment (PE) phenomenon, were rationalized by graph set analysis in terms of the selective dissolut

By utilizing the preferential enrichment (PE) technique, we achieved an improved enantiomeric resolution of DL-leucine (Leu) using a 1:1 cocrystal (DL-1) of DL-Leu and oxalic acid. The crystal structure analysis of DL-1 indicated the occurrence of a

A solvent-assisted solid-to-solid polymorphic transition, which was assumed to be one of the key processes for the occurrence of preferential enrichment (PE), has been proven to occur by means of temperature-controlled video-microscopy (TCVM) and tim

An excellent chiral symmetry-breaking spontaneous enantiomeric resolution phenomenon, denoted preferential enrichment, was observed on recrystallization of the 1:1 cocrystal of dl-arginine and fumaric acid, which is classified as a racemic compound c

The kinetic/thermodynamic origin of preferential enrichment (PE), which is a spontaneous enantiomeric resolution phenomenon applicable to racemic crystals, is described. The mechanism of PE, which was unveiled with respect to the first-generation of

Described is a new strategy using cocrystallization, one of the crystal engineering techniques, to convert a racemic compound crystal into a racemic mixed crystal which can show preferential enrichment, a symmetry-breaking spontaneous enantiomeric re
