Syntesestudier av barkbilleferomonet ipsdienol
(Master thesis, 2020)I denne oppgaven ble det forsøkt å utføre to ulike syntesestrategier for ipsdienol praktisk. Begge disse gir racemisk ipsdienol. Den første strategien ble utført flere ganger, der 2-metylbut-3-yn-2-ol ble dehydrert til ... -
Syntesestudier mot insektferomonet lineatin
(Master thesis, 2017)Målet med oppgaven var å utvikle en ny og bedre syntese av feromonet lineatin (1) gjennom en strategi hvor et eller fler av mellomproduktene også kan benyttes i syntesen av feromonet grandisol (2). Feromonene er tilstede ... -
Syntetisk studier av fenolisk difenylmetan derivater for bruk som modellforbindelser av lignin
(Master thesis, 2020)Kondensasjonsreaksjon av lignin fragmenter er et av problemer for effektiv utnyttelse av lignin. Denne typen reaksjonen ble tidligere studert av Shimada et al[1] der enkelt difenylmetan analog var syntetisert fra blant ... -
Syntetiske studier av nye analoger av 2-metoksyøstradiol med antatt anti-cancer effekter
(Master thesis, 2018)I denne oppgaven har det blitt fremstilt analoger av østrogenmetabolitten 2-metoksyøstradiol. Det har totalt blitt syntetisert sju nye analoge forbindelser. Analogene ble fremstilt ved hjelp av ulike synteseveier. ... -
Syntetiske studier mot analoger av Clausenalansine A
(Master thesis, 2022)Karbazolalkaloider er en type sekundære metabolitter som har vist seg å inneha viktige biologiske aktiviteter. De er derfor svært interessante i utviklingen av nye legemidler. Clausenalansine A er et karbazolalkaloid som ... -
Syntheses of 3-, 4- and 5-membered carbocycles : new methodology on old methods
(PhD Thesis;2015:94, Doctoral thesis, 2020-11-13)The main focus of this thesis was to use new methodology on already well-established methods of preparation of 3-membered, 4-membered and 5-membered carbocyclic compounds with the emphasis on improving them. Traditional ... -
