Organic Chemistry Advanced
A.Y. 2024/2025
Learning objectives
The aim of the course is to drive the student to develop a basic knowledge of the organic reactions in the frame of the synthesis of organic compounds. The course has to enable the student to face the understanding of the modern literature concerning the organic synthesis and to plan simple synthetic sequences. The course is accompanied by two or three seminars given by experts of chemical companies that are involved in organic synthesis
Expected learning outcomes
Students will: design of synthesis of organic molecules based on retrosynthetic analysis; use basic concepts for the understanding of the role of reagents, solvents and reaction conditions; suggest reasonable mechanisms to justify the formation of unexpected products; take into account drawbacks associated to the scale-up of particular reactions or preparations
Lesson period: Second semester
Assessment methods: Esame
Assessment result: voto verbalizzato in trentesimi

Course syllabus
Retrosynthetic analysis and synthetic strategies (compounds 1,2 - 1,3 - 1,4 - 1,5 - 1,6 difunctionalized. (7 hs)
Functional group interconversion: a) conversion of alcohols to alkylating agents, b) introduction of functional groups by nucleophilic substitution, c) interconversion of carboxylic acids derivatives. (6 hs)
Protective groups (OH, NH2, CO, COOH): principal protective groups, revision of the mechanisms involved in the principal reactions for the introduction and removal of protective groups. (14 hs)
Oxidation reactions: oxidation of alcohols to aldehydes, ketones and carboxylic acids; addition of oxygen at carbon-carbon double bond; allylic oxidation; oxidative cleavage of carbon-carbon double bond; oxidation of ketones and aldehydes. (10 hs)
Reduction reactions: addition of hydrogen to carbon-carbon multiple bonds; catalytic hydrogenation of carbonyl group; hydrogen transfer; hydride-donors reagents (groups III and IV); dissolving-metal reductions; reductive deoxygenation of carbonyl groups. (7 hs)
Critical analysis of synthetic strategies reported in the literature with reference to the topics of the course. (4 hs)

Assessment methods and Criteria
Written and oral examination. The written exam is usually composed by 6-12 question/exercises related to guided synthesis, reaction mechanisms, synthesis of simple organic molecules and critical analysis of synthetic schemes reported in the recent literature. The oral examination is aimed to deepen the concepts of the written examination.
