There is also described the synthesis of 2,8-dimethylglycoluril and its S-dimer whose isomerization to the more thermodynamic stable C-dimer was just studied.

Glycoluril and especially its derivatives are with the curvature of their structures and ability to form hydrogen bonds ones of the suitable building blocks for larger supramolecular objects. Abstract Glycoluril and especially its derivatives are with the curvature of their structures and ability to form filftype bonds ones of the suitable building blocks for larger supramolecular objects.
Di,er those the most attention is mainly given to its macrocyclic oligomers, host molecules which are called cucurbiturils.

The thesis was defended successfully. The thesis has been checked: Theses on a related topic List of theses with an identical keyword. In an effort to understand the process via these structural difficult molecules are formed and thus dime solve the problem of their poor solubility by invention of generally working method of the synthesis of their derivatives were investigated as the model system of the first stage of their formation the dimerization reactions of the protected glycolurils and consecutive isomerizations of the generated diastereomers.

In addition to this study was also synthesized new derivatives of glycoluril, 1-methyl-4,6-o-xylylenglykoluril and its cyclic ether, which were subsequently used as the precursors for the synthesis of the dimer and trimer glycoluril structures. This diploma thesis is namely focused on the isomerization of the S-dimer of 2,8-dimethylglycoluril in the presence of hydrochloric acid which was contrary to formerly studied reactions chosen with respect to the real conditions of the cucurbituril synthesis.

This reaction was characterized by NMR methods and was determined both its kinetic and thermodynamic parameters. Furthermore the cross-over experiment revealed that this conversion is intermolecular process.
