Asymmetric Organic Chemistry II
The teaching program on asymmetric organic chemistry, which began in QOA I, will be continued but with an emphasis on the mechanistic aspects. Material from physical chemistry and gneral organic chemistry courses will be combined to create a wider base in kinetics and thermodynamics with emphasis on asymmetric chemistry for the Bioorganc chemistry Masters course. The interdisciplinarity of this course will be strengthened by interlinking other courses such as computational chemistry and structural analysis.
The following themes will be taught but within a flexible framework and can be adjusted depending upon the profile of the students attending the masters course in Bioorganic chemistry.

The theoretical part will be integrated with the theoretical and practical component. The communication will be performed by existing audio-visual techniques making use of slides. Also will use the chalkboard to a proximity communication and a greater interaction with students. A proactive approach is always required.
The theoretical-practical classes will be coordinated with the lectures and it is intended that there is discussion among all the stakeholders.
-Analysis of a paper
The paper has several transformations.
Each student makes the presentation (10 min) - preparing a compound from the previous one (20% of the evaluation). It involves presentation of the mechanism involved.
-Solving a weekly problem. Individual work. Email by the morning of class. Resolution will be made in class (15min) and / or published in CLIP. (20% of the evaluation)
- Analysis of a drug synthesis published in the literature. Written work. Individual work. (60% of the evaluation) - replacement of the 3 scheduled tests.
Remote assessment (AD) given the conditions determined by COVID-19.
