Recent Advances in Ene Reactions with Carbon Enophiles

open access: yesAdvanced Synthesis &Catalysis, Volume 367, Issue 22, November 28, 2025.
Recent advances in the classical intra‐ and intermolecular ene nexus with carbon enophiles (alkenes, alkynes, arynes, and allenes) show a considerable increase in structural complexity and an enormous potential for functional applications in polymer science.

A multifunctional sesquiterpene synthase integrates with cytochrome P450s to reinforce the terpenoid defense network in maize

open access: yesThe Plant Journal, Volume 124, Issue 3, November 2025.
SUMMARY Terpenoids, the largest and most structurally diverse class of plant natural products, play essential roles in maize defense and ecological interactions. In this study, we identified and functionally characterized a sesquiterpenoid‐based defense pathway in maize centered on α‐santalenoic acid, a pathogen‐inducible sesquiterpenoid antibiotic ...

Electroepoxidation of natural and synthetic alkenes mediated by sodium bromide [PDF]

open access: yes, 2009
Electroepoxidation of synthetic alkenes (styrene, trans-stilbene and trans-b-methylstyrene) and of some natural terpenes (limonene, terpinolene, geraniol, a-terpinene, g-terpinene and a-terpineol) mediated by sodium bromide was performed in MeCN:H2O (4:

Iridoid and Acyclic Monoterpene Glycosides, Kankanosides L, M, N, O, and P from Cistanche tubulosa

open access: yesChemical and Pharmaceutical Bulletin, 2010
Three iridoid glycosides, kankanosides L, M, and N, and two acyclic monoterpene glycosides, kankanosides O and P, were isolated from fresh stems of Cistanche tubulosa (Orobanchaceae) together with eight iridoid glycosides, five acyclic monoterpene glycosides, three phenylpropanoid glycosides, and four lignan glycosides. Their structures were elucidated

Seasonal cycle and temperature dependence of pinene oxidation products, dicarboxylic acids and nitrophenols in fine and coarse air particulate matter [PDF]

open access: yes, 2010
Filter samples of fine and coarse air particulate matter (PM) collected over a period of one year in central Europe (Mainz, Germany) were analyzed for water-soluble organic compounds (WSOCs), including the α- and β-pinene oxidation products pinic acid ...

Discovery and characterisation of terpenoid biosynthesis enzymes from Daphniphyllum macropodum

open access: yesBMC Plant Biology
Terpene synthase (TPS) enzymes are known to be pivotal in the biosynthesis of terpenoids in plants and microbes. These enzymes catalyse the transformation of ubiquitous acyclic prenyl diphosphate substrates into diverse hydrocarbon skeletons.

Current and Potential Use of Citrus Essential Oils. [PDF]

open access: yes, 2013
Since the Middle Ages, citrus essential oils (EOs) have been widely used for their bactericidal, virucidal, fungicidal, antiparasitical, insecticidal, medicinal and cosmetic proprieties. Also nowadays, they find important applications in pharmaceutical,

Influence of two acyclic homoterpenes (Tetranorterpenes) on the foraging behavior of anthonomus grandis Boh [PDF]

open access: yes, 2016
Previous studies have shown that the boll weevil, Anthonomus grandis, is attracted to constitutive and conspecific herbivore-induced cotton volatiles, preferring the blend emitted by cotton at the reproductive over the vegetative stage.
