Abstract
U ovom radu opisana je sinteza novih derivata 2-benzoksazolinona u svrhu ispitivanja njihove biološke aktivnosti. Reakcijom nukleofilne supstitucije 5-supstituiranih 2-aminofenola i 1,1`-karbonildiimidazolom u tetrahidrofuranu pripravljeni su 5-supstituirani benzo[d]oksazol-2-oni (1a–c). 5-supstituirani N-propargilbenzo[d]oksazol-2-oni (2a–c) priređeni su reakcijom propargiliranja 5-supstituiranih benzo[d]oksazol-2-ona (1a–c) s propargil-bromidom u acetonu uz prisustvo kalijeva karbonata kao baze. Različito supstituirani 1-azidobenzeni (3a–e) potrebni za klik reakciju sintetizirani su reakcijom odgovarajućih supstituiranih anilina s natrijevim azidom u vodenoj otopini natrijeva nitrita. Huisgenovom 1,3-dipolarnom cikloadicijom kataliziranom bakrom N-propargiliranih benzoksazolona (2a–c) i odgovarajućih azidobenzena (3a–e) dobiveni su ciljani derivati benzoksazolinona supstituirani 1,2,3-triazolnim prstenom (4a–8c). Strukture sintetiziranih spojeva potvrđene su spektroskopijom 1H- i 13C-NMR.
Abstract (english)
This paper describes the synthesis of new 2-benzoxazolinone derivatives with the aim of evaluating their biological activity. 5-substituted benzo[d]oxazol-2-ones (1a–c) were obtained by nucleophylic reaction of 5-substituted 2-aminophenols with 1,1`-carbonyldiimidazole in the tetrahydrofuran. 5-substituted N-propargylbenzo[d]oxazol-2-ones (2a–c) were prepared by the propargylation reaction of 5-substituted benzo[d]oxazol-2-ones (1a–c) with propargyl bromide in the acetone and in the presence of potassium carbonate as a base. Differently substituted 1-azidobenzenes (3a–e) were synthesized using corresponding substituted anilines with sodium azide in an aqueous solution of sodium nitrite. Finally, targeted benzoxazolinone derivatives substituted with 1,2,3-triazole ring (4a–8c) were prepared by copper catalyzed Huisgen's 1,3-dipolar cycloaddition reaction of N-propargylated benzoxazolones (2a–c) and corresponding azidobenzenes (3a–e). The structures of the synthesized compounds were confirmed by 1H- and 13C-NMR spectroscopy.
