Synthesis of Novel Fused N-Heterocyclic [2.2]Paracyclophanes Using C-H Activation/Annulation
Kepková, Klementýna ; Nečas, David (advisor) ; Matoušová, Eliška (referee)
This bachelor thesis is focused on the development of a new methodology leading to a novel type of N-heterocyclic [2,2]Paracyclophanes (we can also view these compounds as isoquinoline derivatives) based on directed C-H activation/annulation process. Within the thesis, necessary [2,2]Paracyclophane derivatives containing appropriate directing group and non-commercial alkynes have been prepared. Suitable catalytic conditions for the C-H activation/annulation reaction sequence have been found and subsequently optimized. Finally, to demonstrate the applicability of that method, several new N-heterocyclic [2,2]Paracyclophane derivatives have been prepared and characterized successfully. Key words: [2.2]Paracyclophane, C-H activation, annulation, Isoquinoline, directing group

Synthesis of Azafluoranthene Derivatives via C-H Activation/Annulation Process.
Hladík, Ondřej ; Nečas, David (advisor) ; Rýček, Lukáš (referee)
The azafluoranthenes are a small group of natural substances, occuring in tropical vines from Menispermaceae family. They display promising medicinal effects (such as anti-HIV, cytotoxic activity) and other biological activities have been predicted. This bachelor thesis is focused on the synthesis of azafluoranthene core via directed C-H activation/annulation process. Firstly, required starting compounds have been prepared. In the next step, suitable catalytical conditions enabling the crucial transformation have been found and optimized. Finally, the applicability of the developed methodology has been confirmed by the synthesis of several new 1-azafluoranthene derivatives. Keywords: C-H activation, annulation, 1-azafluorathene, rhodium
