Conjugated ynones in organic synthesis
Nájera, Carmen; Sydnes, Leiv K.; Yus, Miguel (Journal article; Peer reviewed, 2019)This review article will consider the preparation and application of ynones in synthetic organic chemistry. Concerning the preparation of these bifunctional compounds, several methodologies starting from propargyl alcohols, ... -
Diels-Alder reactions with 1,1-diethoxybut-3-yn-2-one and some 1,1-diethoxy-5-hydroxyalk-3-yn-2-ones and their acetates
Hansen, Frank; Sydnes, Leiv K. (Journal article; Peer reviewed, 2020) -
Evaluation of photodegradable chitin synthetase inhibitors for the treatment of salmon lice (Lepeophtheirus salmonis)
Sydnes, Magne Olav; Eikemo, Vebjørn; Espedal, Per Gunnar; Sydnes, Leiv K.; Nilsen, Frank (Journal article; Peer reviewed, 2023)Some photolabile ethanolamine analogues of the chitin synthetase inhibitors diflubenzuron, teflubenzuron, and lufenuron were tested for activity as anti-lice compounds towards salmon lice (Lepeophtheirus salmonis). Two ... -
Formation of an Isomeric Mixture of Dienynes Instead of a Diallene
Sydnes, Leiv K.; Petrova, Susanna M. (Journal article, 2020)Attempts to convert 1,1,2,2,7,7,8,8-octaethoxyocta-3,5-diyne to a symmetric allene by reduction with lithium aluminum hydride failed. Instead reduction accompanied by isomerization occurred and afforded 1,1,2,7,8,8-hexae ... -
Photodegradable antimicrobial agents - synthesis, photodegradation, and biological evaluation
Eikemo, Vebjørn; Sydnes, Leiv K.; Sydnes, Magne Olav (Journal article; Peer reviewed, 2021)Multi-drug resistant (MDR) bacteria are already a significant health-care problem and are making the combat of infections quite challenging. Here we report the synthesis of several new compounds containing an ethanolamine ... -
Photodegradable Antimicrobial Agents: Synthesis and Mechanism of Degradation
Eikemo, Vebjørn; Holmelid, Bjarte; Sydnes, Leiv K.; Sydnes, Magne Olav (Journal article; Peer reviewed, 2022)As a strategy to inactivate antimicrobial agents after use, we designed a range of ethanolamine derivatives where four of them possessed interesting activity. The ethanolamine moiety facilitates photodecomposition, which ...
