8.  Influence of Helical Structured Supramolecular Associates and that of Eutectic Composition on the Distribution of Enantiomeric and Diastereomeric Mixtures between Phases

Authors: E. Pálovics, Z. Szeleczky and E. Fogassy


Abstract:

The driving force of the formation of the homo- and heterochiral associates in the mixtures of chiral compounds is probably the effort of the system to separate the most symmetric associates from the less symmetric ones. The mixtures of chiral molecules self-organize to supramolecular associations (SDE) that can have homo- and heterochiral compositions. The helical and double helix-like structures that provide higher complementarity are produced in the equilibrium processes between these polymer-like associations. The isolated crystals are formed by these structures. The chiral molecules that take part in the processes are organized according to their CODEs, borne by their chemical properties and structure (eutectic composition) and this way they provide the stoichiometry of the crystalline diastereomer precipitating from the solution.
