Abstract
U ovome radu opisana je priprava spoja 7a,: 5,6-diamino-2-propil-1H-benzo [de] izokinolin-1,3 (2H)-diona, u svrhu selektivnog kompleksiranja i fluorescentne kvantifikacije koncentracije selenija. Kao polazni spoj u sintezi spoja 7a odabran je 4-brom-1,8-naftalanhidrid (1). Prvi korak podrazumijevao je prevođenje spoja 1, reakcijom s odgovarajućim primarnim aminima, u njegove imidne derivate (2a, 2b i 2c). Za provođenje daljnjih sintetskih koraka korišten je jedan od pripravljenih imidnih derivata, spoj 2a. Slijedeći korak podrazumijevao je reakciju spoja 2a s natrijevim azidom što je rezultiralo supstitucijom broma azidnom skupinom, nakon čega slijedi redukcija azidne skupine u amino skupinu (4a). Daljnji sintetski koraci obuhvaćaju halogeniranje aromatskog sustava reakcijom spoja 4a s bromnom vodom čime se htjelo postići selektivno uvođenje broma na ortho položaj u odnosu na već prisutnu amino skupinu (5a). Nakon toga slijedi supstitucija broma azidnom skupinom (6a) te u konačnici redukcija novo uvedene azidne skupine u amino skupinu (7a). Strukture većine spojeva pretpostavljene su IR spektroskopijom i/ ili \( ^{1}H \) i \( ^{13}C \) NMR spektroskopijom.
Abstract (english)
In this diploma thesis synthesis of compound 7a, 5,6-diamino-2-propyl-1H-benzo [de] isoquinoline-1,3 (2H)-dione is described. The purpose of synthesis of this compound is selective complexation and fluorescent quantification of selenium concentration. As starting compound in this synthesis 4-bromo-1,8-naphthalanhdride was used (1). In first step compound 1 reacts with different primary amines to give imide derivatives, compounds 2a, 2b and 2c. In the following steps only compound 2a was used as a starting material for preparation of target compund, compound 7a. Compound 2a reacts with sodium azide and this step is including substitution of bromine with azido group (3a). Azido group of compound 3a was reduced to amino group by introduction of hydrogen sulfide into reaction mixture (4a). The following step inolved halogenation of compund 4a by reaction with bromine water to achieve introduction of bromine in ortho position to amino group (5a). Compound 5a by reaction with sodium azide gave compund 6a and finally azido group of compound 6a was reduced by introduction of hydrogen sulfide into reaction mixture to give target compund, 7a.The structures of most compounds were assumed by IR spectroscopy and/or NMR spectroscopy ( \( ^{1}H \),\( ^{13}C \) ).
