Abstract
U ovom radu prikazana je sinteza i spektroskopska karakterizacija pentacikličkih derivata benzimidazola. Za pripravu ciljane molekule korištene su klasične metode organske sinteze dok je posljednji stupanj sinteze potpomognut mikrovalovima. Kondenzacijom spojeva 2 i 3 priređen je aciklički derivat 4. Termičkom ciklizacijom spoja 4 dobiven je ciklički okso derivat 5 koji se prevodi u spoj 6 koji je glavni prekursor za sintezu ciljanog amino supstituiranog cikličkog derivata benzimidazola. Ciljani derivat 7 priređen je nekatalitičkom aminacijom potpomognutom mikrovalovima iz spoja 6. Struktura priređenih spojeva potvrđena je korištenjem 1H i 13C NMR spektroskopije, a spoje 7 je dodatno okarakteriziran UV/Vid i fluorimetrijskom spektroskopijom. Kako bi se provjerila moguća primjena spoja 7 kao senzora za detekciju pH i metalnih kationa, provedene su UV/Vid i fluorimetrijske titracije otopina spojeva s otopinama metalnih soli i u puferima različitog pH.
Abstract (english)
This work presents the synthesis and spectroscopic characterization of pentacyclic benzimidazole derivatives. Targeted molecule was prepared by classical reaction of organic chemistry while the last stage of synthesis was assisted by microwave. Due to the condensation of 2 and 3 acyclic derivative 4 was prepared. By termic cyclization of compound 4 cyclic oxo derivative 5 was prepared which was converted to compound 6 as the main precursor for the synthesis of target amino substituted cyclic benzimidazole derivative. Targeted derivative 7 was prepared by uncatalyzed microwave assisted amination from compound 6. The structure of synthesized compounds were confirmed by means of 1H and 13C NMR spectroscopy, and also the prepared compound 7 were additionally characterized by UV/Vis and fluorimetric spectroscopy. To explore possible application of compound 7 as sensor for detection pH and metal cations, UV/Vis and fluorimetric titrations of aqueous compounds solutions with aqueous solutions of metal salts and with buffer having different pH were performed.
