In this diploma thesis, I have researched immobilised copper-enaminone catalyst, bound onto aminopropyl silica gel, where 4-aminobenzoic acid served as a linker between the silica gel and the enaminone. The enaminone was successfully removed from 1 and 1' with hydroxylamine hydrochloride to give immobilised 4-aminobenzoic acid with a free amino group 2, which was confirmed using IR spectroscopy. This reaction takes place, via cyclisation of hydroxylamine with enaminone, which cleaves from the silica gel. The structure of heterocyclic by-product of this reaction was confirmed using NMR spectroscopy. The binding of new enaminones onto the 'free' amine group was then considered to gain new products 4a–c, but the reactions proved unsuccessful even under harsher conditions. Because of that, copper was coordinated onto starting material 1 to gain the catalyst 5. The prepared catalyst was then tested on a model reaction for the synthesis of bicyclic pyrazolidinone, methyl 6,7-dihydro-7,7-dimethyl-1-(3,4,5-trimethoxyphenyl)-5-oxo-1H,5H-pyrazolo[1,2-a]pyrazole-2-carboxylate (9). The full conversion with this catalyst was confirmed by NMR spectroscopy.
