Non-linear effects in acyclic amino acid-catalyzed direct asymmetric aldol reactions

Non-linear effects were observed in acyclic amino acid-catalyzed direct asymmetric intermolecular aldol reactions. The non-linear effects are due to the equilibrium solid-liquid phase behavior of amino acids. The results suggest that the phase behavior of amino acids linked to asymmetric catalysis may have implications to the evolution of homochirality.
