Descriptors for terpene esters from chromatographic and partition measurements: Estimation of human odor detection thresholds [PDF]
, 2020 We have used gas chromatographic retention data together with other data to obtain Abraham descriptors for 30 terpene esters. These include the air-water partition coefficient, as log Kw, for which no experimental values are available for any terpene ...

Secondary metabolites of alchemilla persica growing in Iran (East Azarbaijan) [PDF]
, 2015 Phytochemical investigations of Alchemilla persica Rothm. growing in Iran were performed taking into account both the volatile and polar constituents. The hydrodistilled essential oil was analysed by GC-MS that revealed the presence of diterpenoids (19.6

PERMANGANATE–PERIODATE OXIDATION: PART VII. THE OXIDATION OF SOME ACYCLIC MONOTERPENES
Canadian Journal of Chemistry, 1965 The reaction of permanganate–periodate with 1-decene and 1-octadecene in aqueous suspension or media containing tert-butanol has been studied. C10-compounds are oxidized almost quantitatively with the aqueous reagent. Myrcene, cis-ocimene, citronellol, citronellal, citronellic acid, geraniol, nerol, linalool, and linalyl acetate are all oxidized in ...

Recent Advances in Ene Reactions with Carbon Enophiles
Advanced 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.

The 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 ...

The initial dynamics of product release in terpene synthases—The case of CotB2
Protein Science, Volume 34, Issue 10, October 2025.Abstract Although the enzymatic mechanisms of terpene synthases have been extensively characterized through experimental and computational studies, the atomistic details underlying the product release process have remained elusive. In this study, we present the first atomistic simulations of the initial stages of product release in a terpene synthase ...
