The effect of host structure on the selectivity and mechanism of supramolecular catalysis of Prins cyclizations. [PDF]

, 2015
The effect of host structure on the selectivity and mechanism of intramolecular Prins reactions is evaluated using K12Ga4L6 tetrahedral catalysts. The host structure was varied by modifying the structure of the chelating moieties and the size of the ...

Asymmetric Reduction of Unactivated Alkenes

Chemistry – A European Journal, EarlyView.
Unactivated alkenes rank among the most inert functional groups in synthesis and their selective reduction remains challenging. This Review charts the evolution from classical metal‐catalyzed hydrogenation to radical hydrogen atom transfer (HAT) and emerging biocatalytic concepts, highlighting how complementary mechanistic strategies, including the ...

Prompt Formation of Organic Acids in Pulse Ozonation of Terpenes on Aqueous Surfaces [PDF]

, 2010
A major atmospheric process, the gas-phase ozonation of terpenes yields suites of products via a cascade of chemically activated intermediates that ranges from primary ozonides to dioxiranes.

Release of multicomponent pheromones from porous fibres

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Surface engineering empowers a polymer exclusion net to serve dual functions: physical exclusion and pheromonal release, allowing for pest control in agricultural crops. In previous work, a net woven from porous fibres releasing simple, single‐component alarm pheromones showed promising results in field tests.

Alternative oxidase (AOX) constitutes a small family of proteins in Citrus clementina and Citrus sinensis L. Osb. [Poster-B186] [PDF]

, 2018
The alternative oxidase (AOX) protein is present in plants, fungi and some invertebrates. It is involved in the mitochondrial respiratory chain, providing an alternative route for the transport of electrons, leading to the reduction of oxygen to form ...

Enzymatic Synthesis of Demethylated Sesquiterpenes From 14‐nor‐Farnesyl Pyrophosphate

European Journal of Organic Chemistry, EarlyView.
The substrate analog 14‐nor‐FPP was synthesised and enzymatically converted with 10 bacterial and fungal sesquiterpene synthases, resulting in the isolation of 12 demethylated sesquiterpenes in yields up to 17%. In most cases the demethyl analogs of the FPP‐derived natural products were obtained, but also different products showing modified ...

Stability of Monoterpene-Derived α-Hydroxyalkyl-Hydroperoxides in Aqueous Organic Media: Relevance to the Fate of Hydroperoxides in Aerosol Particle Phases [PDF]

, 2020
The α-hydroxyalkyl-hydroperoxides [R–(H)C(−OH)(−OOH), α-HH] produced in the ozonolysis of unsaturated organic compounds may contribute to secondary organic aerosol (SOA) aging.

Evaluation of Agave angustifolia as a Sustainable Alternative to Synthetic Pesticides: Phytochemical Composition and Multi‐Trophic Bioactivity

Flavour and Fragrance Journal, EarlyView.
The pesticidal potential of Agave angustifolia by assessing its anti‐nematic, antimicrobial, and insecticidal activities, alongside phytochemical profiling. ABSTRACT Plant diseases caused by fungi, bacteria, nematodes, and viruses contribute significantly to annual crop losses and economic hardship. Reliance on chemical pesticides, over a thousand used
