20.500.12556/RUL-186931 Sinteza 4-okso-4H-pirido[1,2-a]pirimidin-3-diazonijevega tetrafluoroborata Synthesis of 4-oxo-4H-pyrido[1,2-a]pyrimidin-3-diazonium tetrafluoroborate V diplomski nalogi sem po petstopenjskem postopku iz hipurne kisline sintetiziral 4-okso-4H-pirido[1,2-a]pirimidin-3-diazonijev tetrafluoroborat, ki je uporaben intermediat v sintezi heterociklov in biokonjugaciji. Končni produkt in vse intermediate sem okarakteriziral z IR in 1H NMR spektroskopijo, štiri spojine pa tudi z elementno analizo za C, H in N. Ugotovil sem tudi, da se je spojina 3-amino-4-okso-4H-pirido[1,2-a]pirimidin ob obarjanju iz raztopine izločila v obliki dihidrokloridne soli. In this thesis 4-oxo-4H-pyrido[1,2-a]pyrimidin-3-diazonium tetrafluoroborate, a useful intermediate in the synthesis of heterocycles and bioconjugation, was synthesized in five steps from hippuric acid. The final product and all intermediates were characterized by IR and 1H NMR spectroscopy; four out of five compounds were also characterized by elemental analysis for C, H, and N. I also found out that 3-amino-4-oxo-4H-pyrido[1,2-a]pyrimidine precipitated from the solution as a dihydrochloride salt. 4-okso-4H-pirido[1 2-a]pirimidin-3-diazonijev tetrafluoroborat organska sinteza biokonjugacija fluorescenca diazonijeve soli 4-oxo-4H-pyrido[1 2-a]pyrimidine-3-diazonium tetrafluoroborate organic synthesis bioconjugation fluorescence diazonium salts true false false Slovenski jezik Angleški jezik Diplomsko delo/naloga 2026-09-07 11:10:02 2026-09-07 11:10:04 2026-09-08 04:19:38 0000-00-00 00:00:00 2026 0 0 0000-00-00 NiDoloceno NiDoloceno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 1970-01-01 26213 Koman_Jernej_-_Sinteza_4-okso-4H-pirido[1,2-a]pirimidin-3-diazonijevega_tetrafluoroborata.pdf Koman_Jernej_-_Sinteza_4-okso-4H-pirido[1,2-a]pirimidin-3-diazonijevega_tetrafluoroborata.pdf 1 049DCB5A8F280DB19DA546B4956627C3 a79aa5f97ecbb700d710f6761a9f892a0b6f2cc6df37eb14e188c6c3dc36c40c e656040d-aa9b-11f1-8bc5-0050569b8976 https://repozitorij.uni-lj.si/Dokument.php?lang=slv&id=246326 Fakulteta za kemijo in kemijsko tehnologijo 0 0 0
