Course objectives
Main objectives can be summarized as follows:
to discuss basic principles of organic stereochemistry with preference to to a symmetry-based approach to structures, ligands, faces and reaction classification;
to understand chirality as a condition sine qua non for enantiomerism and enantiodifferentiation;
to discuss the time-dimension in connection with intramolecular dynamism and time-scale of instrumental methods;
to point out problems of the origin of homochirality in living systems;
to learn about topological stereochemistry.
