Abstract

Asymmetric molecular and supramolecular systems are characterized by: i. the circular dicroism in the angular distribution of valence photoelectrons emitted from randomly oriented chiral molecules by their interaction with circularly polarized VUV light; ii. the different stability and reactivity of diastereomeric aggregates. Both these aspects may have some relationship with the \"chiral enrichment mechanism\" of chirogenesis, based on the preferential destruction of one enantiomer of a racemate by interaction with a chiral agent, whether a massive species or a circularly polarized photon. The most recent spectroscopic and mass spectrometric studies on this topic are reported in the present mini-review (literal)
