Great emphasis will be placed on knowledge of organic chemistry, namely synthesis and tactics and strategies of functional groups protection. While in small saturated heterocyclic circles, the exercise will discuss in detail the stereochemical aspects of opening these circles, in mid-size heterocycles, the emphasis will be placed on modern transformations of these systems (e.g. palladium-catalyzed transformations). All the reactions discussed by the lecturer were used in his research and therefore, in addition to theory, the tips and tricks of practical organic chemistry will be discussed as well. During the exercise, mechanisms of organic reactions such as fragmentation, nucleophilic aromatic substitutions, cycloadding, etc. will be repeated as well as physico-chemical properties of functional groups (e.g. pKa values). |

In order to successfully complete the course, it is necessary to complete both the written and oral parts of the exam. If you obtain more than half the number of points from the written part, the oral exam follows (analysis of the test result and supplementary questions). |

The course follows a course in organic chemistry and ideally in organic synthesis. Knowledge of metal-catalyzed reactions is welcome, but is not a necessity. The course fits the profile of a future graduate of Organic Chemistry/Medicinal Chemistry. |
