Acid/base properties and reactivity of square planar complexes
DVOŘÁČKOVÁ, Olga
Complexes of platinum and other transition metals are important compounds with many applications including anticancer treatment. This thesis is based on the computational studies dealing with the properties and reactivity of square planar complexes. We showed that the central metal atom acts as a Lewis acid in standard coordination bonds but is able to interact as a Lewis base when being in contact with a Lewis acid. Substitution(s) of the nonleaving ligand(s) enabled a fine-tuning of the reactivity of Pt(II) compounds.
Enantioselective allylation of thiophene-2-carbaldehyde
Motloch, Petr ; Kotora, Martin (advisor) ; Veselý, Jan (referee)
The first part of the bachelor thesis deals with enantioselective allylation of thiophene-2- carbaldehyde to the corresponding chiral homoallylic alcohol by using chiral Lewis bases as catalysts. The highest asymmetric induction achieved was 97 % ee. The second part concerns application of the prepared chiral homoallylic alcohol as the crucial intermediate for synthesis of antidepressant (S)-duloxetine. Key words enantioselective, allylation, Lewis base, thiophene-2-carbaldehyde, duloxetine
