Abstract

Cilj ovog rada je pripremiti asimetrične derivate skvareinske kiseline kroz nekoliko koraka. Prvi korak odnosi se na sintezu sekundarnih amina, pri čemu su reakcijom litiranja i nukleofilne aromatske supstitucije dobiveni spojevi 1 i 2. Reakcijom alkiliranja 3,5-dimetoksianilina pripravljeni su amini 3 - 6, kao potencijalni prekursori u daljnjoj reakciji kondenzacije i priprave ciljanih asimetričnih skvareina. Svi produkti su izolirani i okarakterizirani spektroskopskim metodama.

Abstract (english)

The aim of this work is to prepare asymmetric derivatives of squaric acid through several steps. The first step relates to the synthesis of secondary amines, whereby the reaction of lithium and nucleophilic aromatic substitution yields compounds 1 and 2. The alkylation reaction 3,5-dimethoxyaniline prepared amines 3 - 6, as potential precursors in the further condensation reaction and preparation of targeted asymmetric squareins. All products were isolated and characterized by spectroscopic methods.
