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 ... -
Synthesis of All-Z-1,6,9,12,15-Octadecapenten-3-one, A Vinyl Ketone Polyunsaturated Marine Natural Product Isolated from Callysponga sp.
(Journal article; Peer reviewed, 2014)Abstract: The synthesis of the marine natural product 1,6Z,9Z,12Z,15Z-octadecapentaen-3-one (1) has been achieved by two different routes starting from the ethyl esters of eicosapentaenoic acid (EPA) and docosahexaenoic ... -
Synthesis of glycoconjugates utilizing the regioselectivity of a lytic polysaccharide monooxygenase

Synthesis of Racemic β-Chamigrene, a Spiro[5.5]undecane Sequiterpene
(Journal article; Peer reviewed, 2014)The present paper describes a total synthesis of racemic β-chamigrene (1), a sesquiterpene with a spiro[5.5]undecane carbon framework. Compared with previously reported β-chamigrene syntheses, we were able to reduce the ... -
Synthesis of some marine natural product fatty acid derivatives
(PhD Thesis;2016:74, Doctoral thesis, 2020-11-24)The research presented in this thesis puts forth total syntheses of two marine natural products: (-)-mucosin and (+)-crucigasterin 277. Both syntheses focus on producing enantiopure natural products derived from commercially ... -
Synthesis of the Methyl Ester of MaR2n-3 DPA
(Master thesis, 2019)This master thesis presents the first synthesis of the methyl ester of the specialized pro-resolving mediator named MaR2n-3 DPA. The stereoselective synthesis is based on a Z-selective Lindlar reaction, a Sonogashira ... -
