00152 - Organic Chemistry II

Learning outcomes

The aim of the course is to widen and deepen the knowledge of organic chemistry. The main C-C forming reactions will be presented and synthetic strategies will be discussed. The chemical properties of several classes of organic compounds, mostly of natural origin, will
be presented, together with synthetic approaches leading to them.
The student will acquire a deeper understanding of physical and chemical properties of organic compounds, which will allow an analytical approach to problem-solving and autonomous study in the field of organic chemistry.

Course contents

• Heterocyclic aromatic compounds: pyrrole, furan, thiophene, pyridine and their derivatives: structure and reactivity.
• Nucleosides, nucleotides and nucleic acids.
• Free radicals and radical reactions.
• Stereochemistry: isomers classification, stereoisomers classifications, chirality: centre, axis, plane, helix, determination of enantiomeric excess and optical purity, basics of resolution techniques and asymmetric synthesis.
• Sugars: monosaccharides, disaccharides, polysaccharides: structure and reactivity.
• Aminoacids, peptides and proteins.
• Working out organic structures: C-C bond forming reactions, enolate chemistry, protecting groups, synthetic equivalents, retrosynthetic analysis.
• Exercises on retrosynthetic analysis and synthesis planning.
• Brief overview of the main synthetic approaches to the preparation of amino acids and peptides.

Assessment methods

In the absence of restrictions imposed by specific collective emergencies, the final examination, aiming at ascertaining the student's acquired skills, will consist of both a written and an oral test. The written test is the main one, where students will be presented with 3 questions, pertaining the course topics, which must be answered in 2 hours time (books, notes etc. are not allowed). A maximum of 10 points will be given for each question. Students ranking above 17/30 will take the oral. The oral test (45 min ca.) is meant for a more precise evaluation of the candidate and it will have the written test as the starting point. Enrolment via AlmaEsami.
