Acknowledgement

I would like to first and foremost thank my advisor and mentor, Prof. Dr. Dirk Trauner.
Joining the group as his first PhD student at the LMU München was truly a special
experience. His enthusiasm for and encyclopedic knowledge of both chemistry and
general science has been a constant source of motivation and crucial for the success
of my projects. I especially appreciated his trust in my work and the freedom he
granted me to explore new ideas and solve problems at hand.
Thanks to Prof. Dr. Karaghiosoff for appraising my dissertation.
And thanks to Prof. Dr. Hoffmann-Röder, Prof. Dr. Bracher, Prof. Dr. Langhals and
Prof. Dr. Heuschmann for being available as examiners in my defense.
I would like to thank my wife Aylin, who is “solid as rock” in my life. She constantly
supported and motivated me since I met her for the very first time. Such a
performance would have been not possible without her wonderful character, her
patience and her immense understanding. You have given this work and my life great
meaning. I love you!
I owe my family so much that I don’t even know where to start. Their support during
my whole education is the reason why I made it this far. My parents believed in
providing me with the best possible education no matter the sacrifice. I cannot thank
them enough for their unconditional love.
I’d like to thank my uncle Mümtaz for his guidance in educational questions.
Upon spending most of my time in the laboratory, I quickly learned the true value of
my labmate and close friend Christian A. (A like awesome) Kuttruff. He truly had a big
impact on my dissertation. His help in computational issues, discussions about
chemistry and private life, exchange of ideas, squash games, going on vacation
(Huttanz!) and his good taste in music made my PhD very enjoyable.
Special thanks go to all my labmates from the Trauner group, namely Jennifer Lachs,
Ingrid Chen, T. J. Kimbrough, Anastasia Hager, Christian A. Kuttruff and Elena
Herrero-Gómez, for being good colleagues and creating a nice and peaceful lab
atmosphere. Further, I would like to acknowledge, Eddie Myers, Robert Webster,
David Woodmansee, Julien Lefranc and Christian A. Kuttruff for their help proof-
reading applications, publication manuscripts and this dissertation.
Thanks also to Arunas Damijonaitis and Julien Lefranc for taking over my projects.

I’d like to express my gratitude to the people who made my dissertation possible:
Staff from the Trauner Group: Tobias Kauer, Petra Böhrer, Carrie Louis, Dr. Martin
Sumser and especially Heike Traub for being supportive in all kind of bureaucratic
issues;
Staff from the LMU Analytic department: Dr. Spahl and Frau Kosak for mass
spectroscopic data, Dr. Stevenson and Fr. Dubler for NMR data and especially Dr.
Mayer for his patience and efforts in finding suitable crystals for x-ray analysis.
I am also grateful to many teachers that fostered my interest in organic chemistry.
These people include Frau Engelberger, Frau Geisler, Dr. Dimitrios Mihalios, Dr.
Sebastian Brandes, Dr. Birte Basler, Dr. Roger Norcross, Prof. Thorsten Bach and
Dr. Herbert Schuster.
I’d like to thank Bastian Sauerer for having funny pizza dinners with progress reports.
During my PhD studies I had the joy to supervise a number of very motivated
undergraduate co-workers, who spend a lot of time with me in the lab and were all
very hard-working: Sebastian Götte, Christine Sturm, Ufuk Borucu, Caroline Pflüger,
Christine Hieke, Ebru Zeynep Serdar, Andreas Ahlers, Hiroki Nakatsu, Johannes
Feierfeil and Klaus Speck. Thank you all for being so supportive.
Last but not least, special thanks go to my close friends Ömer Özcan (Bergtürke),
Akram Barkia (Camel) and Zoran Pranjic (RedNinja), who have been as supportive
as friends can possibly be and challenged me in go-cart races, wakeboarding and
rafting.
