Enantioselective synthesis of (-)-(1R,2R)-1,2-dihydrochrysene-1,2-diol
Lorentzen, Marianne; Sydnes, Magne Olav; Jørgensen, Kåre Bredeli (Peer reviewed; Journal article, 2014)A general chiral building block containing the 1R,2R-trans-diol moiety was constructed utilizing the stereoselective Shi-epoxidation reaction on a tetralone scaffold assembled by a Negishi cross-coupling on N,N-diethylbenzamide. ... -
Optimization of acid catalyzed transesterification of jatropha and rapeseed oil with 1-butanol
Bynes, Adrian N.; Eide, Ingvar; Jørgensen, Kåre Bredeli (Peer reviewed; Journal article, 2014-08)The acid catalyzed transesterification of rapeseed and jatropha oil with 1-butanol was studied by varying temperature, reaction time, butanol/triglyceride ratio and the amount of sulfuric acid. A full factorial design ... -
Regiospesific synthesis of dimethylphenanthrenes
Bøhme, Thomas Andre; Lorentzen, Marianne; Jørgensen, Kåre Bredeli (Peer reviewed; Journal article, 2017-05)The dimethylated phenanthrenes 2,3-dimethylphenanthrene (4a), 2,7-dimethylphenanthrene (4b), 2,6-dimethylphenanthrene (4c) and 1,7-dimethylphenanthrene (4d) have been prepared in gram-quantities by a short sequence of ... -
Total synthesis of tubastrine and 3-dehydroxy tubastrine by microwave-assisted cross-coupling reactions
Lorentzen, Marianne; Bayer, Annette; Sydnes, Magne Olav; Jørgensen, Kåre Bredeli (Journal article, 2015-10)The first syntheses of tubastrine and 3-dehydroxy tubastrine are described. The target compounds were prepared in four consecutive steps from commercially available starting materials. The central scaffold was formed by a ... -
Ultrasound-assisted synthesis of novel 1,2,3-triazoles coupled diaryl sulfone moieties by the CuAAC reaction, and biological evaluation of them as antioxidant and antimicrobial agents
Mady, Mohamed F.; Awad, Ghada E.A.; Jørgensen, Kåre Bredeli (Peer reviewed; Journal article, 2014-09)A series of 1,2,3-triazoles coupled diaryl sulfone containing compounds were synthesized by the copper-catalyzed azide-alkyne 1,3-dipolar cycloaddition (CuAAC) reaction in benign solvents under ultrasound irradiation. In ...
