Chemistry of the carbonyl group; Woodward-Hoffman rules (Diels-Alder reactions, sigmatropic rearrangements); basic heterocyclic chemistry (synthesis and reactivity of pyridine, pyrrole, furan and thiophene); oxidation and reduction methods in synthesis; spectroscopy (1H NMR, 13C NMR and mass spectrometry) and structure elucidation; stereochemistry and stereochemical aspects of reactivity of selected alicyclic compounds (cyclohexane derivatives and decalins).
