Abstract

U sklopu ovog rada provedena je sinteza asimetričnih derivata skvareinske kiseline, kroz nekoliko koraka. Prvi stupanj odnosi se na pripravu alkoksidnog derivata skvareinske kiseline (1 i 1'), kako bi u sljedećem koraku bilo omogućeno uvođenje sekundarnog amina. Konačni produkti 11 – 16 dobiveni su reakcijom kondenzacije prethodno dobivenih aminoskvaraina 2 – 4 i odgovarajućeg aminoalkohola. Aminoalkohol 8 – 10 dobiven je neovisnom sintezom u dva stupnja. Prvi stupanj je reakcija aminacije kojom se uvodi sekundarni amin u organsku molekulu dok se u drugom stupnju dealkiliranjem dobiva konačni produkt. Svi spojevi su u potpunosti spektroskopski okarakterizirani.

Abstract (english)

As part of this work, the synthesis of asymmetric derivatives of squaric acid was performed through several steps. The first stage refers to the preparation of the alkoxide derivative of squaric acid (1 and 1'), in order to enable the introduction of the secondary amine in the next step. The final products 11 – 16 were obtained by the condensation reaction of previously obtained aminosquarains 2 – 4 and the corresponding amino alcohol. Amino alcohols 8 – 10 were obtained by independent synthesis in two steps. The first step is an amination reaction that introduces a secondary amine into the organic molecule, while the final product is obtained in the second step by dealkylation. All compounds have been fully spectroscopically characterized.
