title: Amplification of chirality in hydrogen-bonded tetrarosette helices.
abstract: The amplification of chirality in hydrogen-bonded tetrarosette assemblies under thermodynamic equilibrium is described. The extent of the chiral amplification obtained by means of "sergeants-and-soldiers" experiments depends only on the structure of the assembly and it is independent of the methodology used for the formation of the tetrarosette assemblies. The difference in free energy (deltaG(o)(M/P)) between the M- and P-diastereomeric helices is up to 40 times higher than for double rosette assemblies.
