Responsible
Lesson period
Second semester
Prerequisites for admission
Theoretical course:
Good knowledge of organic chemistry I and II
Laboratory:
Basic knowledge of synthetic techniques acquired in a laboratory of organic synthesis
Assessement methods and criteria
Theoretical course: written exam relating to the synthesis of organic compounds (10 exercises; marks for each exercise: 0-3) followed by discussion of the results.
Laboratory module: evaluation of the laboratory activity and of the report delivered by the student
The final mark is the result of the weight average of the mark of the written exam and of the laboratory activity.

Course syllabus
The practical activities are listed below:
1. on-line bibliographic researchers regarding the products to be synthesized
2. synthesis of reagents and products exploiting different particular techniques related to: a) use of techniques for reactions under inert atmosphere and anhydrous solvents; b) use of reagents sensible to wet and air
3. use of gas-chromatography
4. use of polarimetry
6. identification of suitable analytical procedures (e.g. MS and NMR spectroscopic analyses) aimed to structural determination and characterization of different products synthesized
Teaching methods
Practical experiences in advanced organic synthesis laboratory and computer laboratory practice.
