Objectives
THE COURSE AIMS TO PROVIDE INFORMATION AND METHODS FOR THE RESOLUTION OF COMPLEX PROBLEMS OF CURRENT ORGANIC SYNTHESIS. PARTICULAR EMPHASIS WILL BE DEVOTED TO THE APPLICATIONS OF CATALYSTS OF VARIOUS NATURE IN THE SYNTHESIS AND TRANSFORMATIONS OF ORGANIC COMPOUNDS, IN THE STUDY OF MECHANISMS OF THE MAIN TRANSFORMATIONS, THE PROPERTIES OF CHIRAL MOLECULES AND ENANTIOSELECTIVE CATALYTIC METHODS.

THE MAIN KNOWLEDGE ACQUIRED BY THE STUDENTS WILL REGARD TO:

- RELATIONSHIP BETWEEN MOLECULAR STRUCTURE AND EXPERIMENTAL REACTIVITY OF MONO- AND POLY-FUNCTIONAL MOLECULES.
- APPLICATIONS OF METAL CATALYSIS IN THE MAIN TRANSFORMATIONS AND ENANTIOSELECTIVE VERSIONS OF THESE REACTIONS.
- RECENT DEVELOPMENTS OF ORGANOCATALYSIS IN ASYMMETRIC SYNTHESIS.
- MECHANISTIC FEATURES OF MAIN REACTIONS.
- METHODOLOGICAL STRATEGIES FOR THE SYNTHESIS OF PHARMACOLOGICALLY ACTIVE CHIRAL PRODUCTS.

THE MAIN SKILLS DEVELOPED BY THE STUDENTS WILL BE:

- SOLVING PROBLEMS RELATED TO THE SYNTHESIS AND TRANSFORMATION OF COMPLEX MOLECULES.
- CRITICAL ANALYSIS OF EXPERIMENTAL DATA AND OF THE STEREOCHEMICAL ASPECT OF A REACTION.
- APPLICATION OF REACTIONS PROMOTED BY CATALYSTS TO SUBSTRATES OF DIFFERENT NATURE.
- INSTRUMENTAL ANALYSIS FOR THE DETERMINATION OF THE PURITY OF STEREOISOMERIC MIXTURES OF ORGANIC COMPOUNDS
Prerequisites
BASIC ORGANIC CHEMISTRY AT A BACHELOR DEGREE LEVEL

Teaching Methods
THE COURSE CONTEMPLATES LECTURES WITH SUPPORT OF ELECTRONIC PRESENTATIONS AND THE SOLVING OF RELEVANT PROBLEMS ON THE BLACKBOARD. ALL TEACHING MATERIALS WILL BE MADE AVAILABLE TO STUDENTS AT THE END OF EACH LESSON AS FILES IN PDF FORMAT.
MOREOVER, EXERCISES WILL BE PROVIDED ON THE APPLICATIONS OF THE MECHANISMS OF THE MAIN REACTIONS STUDIED IN THE COURSE.
Verification of learning
THE EXAM OCCURS EXCLUSIVELY THROUGH AN ORAL INTERVIEW ON THE
THEORETICAL AND METHODOLOGICAL CONTENTS AS
INDICATED IN THE COURSE PROGRAM. THE AIM IS TO ESTABLISH THE LEVEL OF
KNOWLEDGE AND CAPACITY OF
UNDERSTANDING REACHED BY THE STUDENT, AND TO VERIFY THE ABILITY OF
THE PRESENTATION USING THE
APPROPRIATE TERMINOLOGY.
