Abstract
Derivati kinazolinona su heterociklički spojevi koji su u fokusu istraţivanja moderne medicine i kemije već nekoliko desetljeća. Konvencionalne laboratorijske sinteze ovih spojeva, koje uključuju različita organska otapala i katalizatore, često štetne za okoliš i samog čovjeka, te se stoga teţi pronalasku novih okolišno prihvatljivih zelenih metoda priprave. Cilj ovoga diplomskoga rada bio je sintetizirati različite derivate kinazolinona iz supstituiranih antranilnih kiselina, anilina i trimetilortoformijata s naglaskom na zeleni pristup. Zelene sinteze su uključivale reakcije potpomognute ultrazvučnim zračenjem, mikrovalnim zračenjem te mehanokemijsku sintezu, uz upotrebu eutektičkih otapala. Eutektička otapala pripravljana su na bazi kolin-klorida i različitih amida, karboksilnih kiselina, alkohola i ugljikohidrata u različitom molarnom omjeru. Prije svake sinteze provedena je optimizacija na modelnoj reakciji kako bi se našlo najprikladnije eutektičko otapalo, temperatura i vrijeme reakcije. Budući da kinazolinoni posjeduju antibakterijsko djelovanje, provedeno je i antibakterijsko ispitivanje.
Abstract (english)
Quinazolinone derivatives are heterocyclic compounds that have been the focus of research in modern medicine and chemistry for several decades. Conventional laboratory syntheses of these compounds, which include various organic solvents and catalysts, are often harmful to the environment and to humans, and therefore efforts are being made to find new environmentally friendly green preparation methods. The aim of this thesis was to synthesize different quinazolinone derivatives from substituted anthranilic acids, aniline and trimethylorthoformate with an emphasis on a green approach. Green syntheses included reactions assisted by ultrasound radiation, microwave radiation, and mechanochemical synthesis, with the use of eutectic solvents. Eutectic solvents were prepared on the basis of choline chloride and different amides, carboxylic acids, alcohols and carbohydrates in different molar ratios. Before each synthesis, optimization was carried out on the model reaction in order to find the most suitable eutectic solvent, temperature and reaction time. Since quinazolinones have an antibacterial effect, an antibacterial test was also carried out.
