Patterns and roles of lignan and terpenoid accumulation in the reaction zone compartmentalizing pathogen-infected heartwood of Norway spruce
Nagy, Nina Elisabeth; Norli, Hans Ragnar; Fongen, Monica; Østby, Runa Berg; Heldal, Inger; Davik, Jahn; Hietala, Ari Mikko (Peer reviewed; Journal article, 2022)Tree defense against xylem pathogens involves both constitutive and induced phenylpropanoids and terpenoids. The induced defenses include compartmentalization of compromised wood with a reaction zone (RZ) characterized by ... -
Two-Phase Dibromocyclopropanation of Unsaturated Alcohols Using Flow Chemistry
Østby, Runa Berg; Didriksen, Terje; Antonsen, Simen Gjelseth; Nicolaisen, Steinar Sollien; Stenstrøm, Yngve H. (Peer reviewed; Journal article, 2020-05-19)Dibromocyclopropanations are conventionally done by addition of dibromocarbene to alkenes under phase-transfer conditions in batch reactions using a strong base (50% NaOH (aq)), vigorous stirring and long reaction times. ... -
