WebIn internal selection pressure resolution, self-transformation and crystallization-induced diastereomeric resolution have been successfully used to challenge dynamic systems. The technique was, for example, used to identify the best diastereomeric substrate from a large and varied dynamic system in a single resolution reaction.

WebDynamic atropselective resolutions of the peptide–biphenyl hybrids 3–5 were achieved by crystallization from methanol solution. These compounds were studied by single-crystal X-ray diffraction. These hybrids crystallize in highly ordered structures kept by an extensive array of intramolecular and intermolecular hydrogen bonds.
