Abstract
U okviru ovog rada provedena je sinteza i strukturna karakterizacija novih konjugata N-supstituiranih benzimidazola. Ciljani amidino supstituirani benzamidi priređeni su uobičajenim metodama organske sinteze i mikrovalovima potpomognutom sintezom. U prvom sintetskom koraku 4-N supstituirani 3-nitrobenzonitrili 2 i 3 priređeni su mikrovalovima potpomognutom aminacijom 4-klor-3-nitrobenzonitrila 1 uz korištenje odgovarajućeg amina. U drugom koraku spojevi 2 i 3 reducirani su u diamino supstituirane benzonitrile 4 i 5 korištenjem SnCl2 x 2H2O. 2-aminobenzimidazoli 6 i 7 priređeni su ciklokondenzacijom spojeva 4 i 5 korištenjem BrCN-a. U zadnjem koraku sinteze priređeni su 2-benzimidazolil supstituirani benzamidi 10, 11 i 12 kondenzacijom spojeva 6 i 7 s odgovarajućim karboksilnim kiselinama 8 i 9. Ciljani amidino supstituirani spojevi 13 i 14 sintetizirani su Pinnerovom reakcijom u kiselom mediju iz odgovarajućeg cijano supstituiranog spoja 10. Strukture priređenih spojeva potvrđene su 1H i 13C NMR spektroskopijom, a tijek Pinnerove reakcije praćen je IR spektroskopijom.
Abstract (english)
This work presents the synthesis and structural characterization of novel conjugates of N-substituted benzimidazoles. Targeted amidino substituted benzamides were prepared by usual methods of organic chemistry and by microwave-assisted reactions. In first step of synthesis, 4-N substituted 3-nitrobenzonitriles 2 and 3 were prepared by microwave-assisted amination of 4-chloro-3-nitrobenzonitrile 1 using the corresponding amines. In second step, compounds 2 and 3 were reduced to diamino-substituted benzonitriles 4 and 5 using SnCl2 x 2H2O. 2-aminobenzimidazoles 6 and 7 were prepared by cyclocondensation of compounds 4 and 5 with BrCN. In the last step of synthesis, 2-benzimidazolyl-substituted benzamides 10, 11, and 12 were prepared by condensation of compounds 6 and 7 with the corresponding carboxylic acids 8 and 9. Targeted amidino substituted compounds 13 and 14 were synthesized by Pinner reaction in acidic medium from corresponding cyano substituted 10. Structures of prepared compounds were confirmed with 1H i 13C NMR spectroscopy, while Pinner recation was monitored by IR spectroscopy.
