Synthesis of chiral secondary amines useful as organocatalysts
 Urban, Michal ; Veselý, Jan (advisor) ; Drahoňovský, Dušan (referee)
This bachelor thesis deals with the preparation of chiral secondary amines, which are used as catalysts in many chemical transformations leading to enantimerically pure compounds. The emphasis of this work is placed on the comparison of the effectiveness of published syntheses those organocatalysts. The first part focuses on the comparison of efficiency and optimization of two methods of preparation Jørgensen's catalyst, the first approach is based on the Z-protected (S)-proline, and in the second approach as starting material was used. The second part deals with the preparation of other Jørgensen's and Hayashi's types of catalysts, via introduction of various silyl functional groups.
