Simple proxies for estimating the concentrations of monoterpenes and their oxidation products at a boreal forest site

open access: yes, 2016
. The oxidation products of monoterpenes likely have a crucial role in the formation and growth of aerosol particles in boreal forests. However, the continuous measurements of monoterpene concentrations are usually not available on decadal timescales ...

Direct Ambient Mass Spectrometry for Food, Beverage, and Agricultural Sample Analysis and Research

open access: yesMass Spectrometry Reviews, EarlyView.
ABSTRACT Ambient and direct mass spectrometry (MS) methods are becoming increasingly used for the rapid analysis of food, beverage and agricultural samples. Novel ionization approaches combined with targeted, or untargeted workflows provide analytical outcomes within a greatly reduced time period compared to traditional separation science coupled with ...

Synthesis of chiral 2-methyl-5,6,7,8-tetrahydroquinolines from naturally occurring monoterpenes [PDF]

open access: yes, 2004
The synthesis is reported of chiral substituted 2-methylpyridines, in which the pyridine rings are annulated at the 5,6-positions to the chiral frameworks originating from (-)-β-pinene, (-)-isopinocampheol and (+)-camphor.

Exploring Unspecific Peroxygenase Selectivity with Diverse Hydrocarbon Substrates

open access: yesChemistryOpen, EarlyView.
Unspecific peroxygenases (UPOs) are versatile enzymes that can be used for different reactions. However, selectivity of UPOs needs to be evaluated for the desired application. Thus, the selectivity of a panel of UPOs was evaluated in this work, and it revealed diverse reactivity profiles depending on the enzyme and substrate.
