Monoterpene ‘thermometer’ of tropical forest-atmosphere response to climate warming [PDF]

, 2017
Tropical forests absorb large amounts of atmospheric CO2 through photosynthesis but elevated temperatures suppress this absorption and promote monoterpene emissions.

Alkali‐Metal Base Catalyzed Electrocyclization of Isoprene Derivatives

Chemistry – A European Journal, EarlyView.
Simple and abundant alkali‐metal base catalysis in combination with Lewis basic polyamines enables the electrocyclization of isoprene‐derived trienes to cycloheptadienes under neat conditions. Mechanistic insight supported by DFT guides a scalable route to seven‐membered carbocycles which, after reduction, give saturated cycloalkanes relevant as ...

Cyclization mechanism of monoterpenes catalyzed by monoterpene synthases in dipterocarpaceae

Synthetic and Systems Biotechnology
Monoterpenoids are typically present in the secretory tissues of higher plants, and their biosynthesis is catalyzed by the action of monoterpene synthases (MTSs). However, the knowledge about these enzymes is restricted in a few plant species. MTSs are responsible for the complex cyclization of monoterpene precursors, resulting in the production of ...

Drying temperatures affect the qualitative–quantitative variation of aromatic profiling in Anethum graveolens L. ecotypes as an industrial–medicinal–vegetable plant

Frontiers in Plant Science, 2023
IntroductionThere are several factors that affect the quality and quantity of active ingredients and essential oil (EO) content, including pre and postharvest practices such as drying conditions. One of the most important factors in drying is temperature
