The course aims to provide students with a more in-depth training in Organic Chemistry from the first basic course, particularly with regard to nomenclature, chemical properties and reactivity of multifunctional compounds; the main classes of organic compounds of biological significance: carbohydrates, amino acids and peptides, lipids; the major heterocyclic systems. Students will gain further knowledge about pericyclic reactions and the fundamental principles of organic synthesis, learning to develop simple synthetic sequences of polyfunctional organic compounds and to apply the principles of modern synthetic strategies for disconnection approaches, formation of carbon-carbon bonds, deprotection protection functional groups.
