Preparation of chiral amides and their use as organocatalysts
Brandejsová, Aneta ; Veselý, Jan (advisor) ; Hrdina, Radim (referee)
This bachelor thesis is focused on preparation of C-9 amino derivatives of Cinchona alkaloids and derived bifunctional squaramide catalysts, which are used as organocatalysts in a wide variety of chemical transformations leading to enantiomerically pure compounds. The first part deals with choosing the most efficient method for the preparation of C-9 amino derivates of Cinchona alkaloids and the synthesis of four selected examples. In the second part, the prepared derivates are used for the synthesis of bifunctional squaramide catalysts, which are further tested in newly designed cyclization reactions.
Optimalization of preparation of bifunctional organocatalysts derived from alkaloids
Formánek, Bedřich ; Veselý, Jan (advisor) ; Drahoňovský, Dušan (referee)
This bachelor thesis deals with the preparation of C−9 Cinchona alkaloid derivatives, which are used in wide variety of asymmetric transformations. First goal is comparison of synthetic aproaches and their effectiveness. In particular of C−9 amino derivatives. This part also examines possible optimization of synthesis individual steps. Second goal of bachelor thesis focuses on preparation bifunctional catalysts based on Cinchona alkaloids.
