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.
Learning outcomes
Student will understand concept of isomerism of chemical compounds;
will be able to work with concepts conformation, configuration, chirality and optical activity;
will be able to chose suitable methods for identification of stereoisomers, determination of their contents in mixtures, and their possible separation;
utilize symmetry for elucidation of heterotopicity of homomorphic ligands and faces;
recognize stereoselective reactions and explain reasons of their selectivity based on steric, stereoelectronic and further effects;
utilize basic chiroptic methods for analysis and identification of chiral compounds.
