Special Synthesis Techniques in Organic Chemistry
A.Y. 2023/2024
Learning objectives
The course intends to explain the basic concepts in the synthesis of complex organic molecules. The most significant methodologies of the modern organic synthesis will be discussed, also including asymmetric ones, with attention to both the general aspects and illustrative applications. Also some special techniques will be described, among the most recent and of wide spread, which are aimed to improve the efficiency, the economy and the environmental impact of the chemical organic synthesis.
Expected learning outcomes
The course allows a consolidation of the knowledge on the general strategies of formation of the single and multiple carbon-carbon bond; provides basic skills of asymmetric synthesis; allows a first contact with special techniques applied to chemical synthesis. The student acquires the ability to solve the synthesis of molecules with different degrees of structural complexity.

Course syllabus
Basic concepts in the modern synthesis of complex organic molecules: in-depth study on alkylation of enolates, aldol reaction, acylation at carbon, conjugate addition of enolates; controlling the geometry of double bonds; elements of stereochemistry, diastereoselectivity (2 cfu).
Synthesis of optically active molecules: kinetic resolution, chiral pool methodology, chiral auxiliaries, asymmetric catalysis; asymmetric catalysis in organic synthesis: metal catalysis, enzymatic catalysis, organocatalysis (1 cfu).
Transition metal complexes in organic synthesis: the basic chemistry of organopalladium complexes; Heck, Sonogashira, Suzuki, Negishi, Stille reactions; olefin metathesis (1 cfu).
Special techniques: microwave, ultrasounds, ionic liquids in organic synthesis; not conventional solvents, polymer supported reagents; solid phase synthesis; flow chemistry (2 cfu).
Within the course, also guided exercises will be proposed to students, aimed to a better understanding of the contents and to a full application in practical examples.
