Objectives
Knowledge and understanding
At the end of course, the student knows the main concepts of organic chemistry needed both for the knowledge of the molecular structure and for the understanding of the reactivity of the main functional groups. Moreover, the student learns the basic concepts of stereochemistry and reaction mechanisms in organic chemistry.
Applying knowledge and understanding
At the end of course, the student knows and understand the spatial arrangement of the carbon structures and knows how to assign the name to the simplest molecules according to the IUPAC nomenclature; the student is able to graphically show the structures through the most commonly used conventions and assign the absolute configuration to the stereocenters. Furthermore, the student knows the reactivity of the functional groups according to the general scheme of the main reaction mechanisms.
Making judgements
The student, at the end of course, is able to collect and understand information useful to express a proper independent opinion. In particular, he must show a critical and proposing spirit in the discussion of issues inherent to natural products and their implications in global health.
Communication skills
The student, at the end of course, has the ability to communicate outward the knowledge he has learned during the Master degree, both toward the scientific community and the labor market. In particular, he must be able to provide clear and direct information on chemical reactivity, with particular emphasis to that of the natural products.
Learning skills
Given the basic training activity of this course, students who have passed the exam are able to undertake the study of other basic and characterizing training activities that have been set in the Master degree.
