Learning objectives

The course aims at providing to the students the knowledge of organic stereochemistry and various stereo- and enatioselective reactions.
The fundamental principles of green chemistry will be discussed in order to evaluate the eco-efficiency of a chemical process. Particular attention will be devoted to heterogeneous catalysis.
The course aims to give information on the chirality of organic molcules and on stere- and enetioselective reactions
