Efficient syntheses of climate relevant isoprene nitrates and (1R,5S)-(−)-myrtenol nitrate

open access: yesBeilstein Journal of Organic Chemistry, 2016
Here we report the chemoselective synthesis of several important, climate relevant isoprene nitrates using silver nitrate to mediate a ’halide for nitrate’ substitution. Employing readily available starting materials, reagents and Horner–Wadsworth–Emmons

Planting for healthy air: Urban biodiversity enhances natural chemical environments

open access: yesPLANTS, PEOPLE, PLANET, EarlyView.
Cities urgently need nature to improve public health, support biodiversity, and increase resilience to climate change. Yet not all green spaces offer the same benefits. In this study, we show that more diverse urban plantings create richer “chemical environments”; subtle, naturally scented atmospheres formed by plant emissions that can influence how ...

How does leaf age affect performance? A comparative study of essential oils from young and mature Eucalyptus globulus leaves in crop protection

open access: yesPest Management Science, EarlyView.
Leaf age influences metabolomic profiling but not bioactivity of Eucalyptus globulus essential oils. Leaf age affects volatile levels of young and adult E. globulus oils, but not their bioactivity. Young leaf essential oil had higher contents of α‐ and β‐pinene. AEEO had higher levels of 1,8‐cineole and trans‐pinocarveol.

Multimodal targets of (‐)‐α‐thujone mediating avoidance behavior of a stored‐products pest, Tribolium castaneum, in response to irritant stimuli

open access: yesPest Management Science, EarlyView.
We identified four kinds of target molecules against (‐)‐α‐thujone associating avoidance behavior in Tribolium castaneum, indicating multimodality. Abstract BACKGROUND The reciprocal evolutionary processes among phytophagous insects and host plants involve host shift in the herbivorous insects in response to defense chemicals, such as plant‐derived ...

Essential oils as bioherbicides: effects of orange and citronella oils on weed germination and early growth

open access: yesPest Management Science, EarlyView.
Essential oils from orange and citronella showed dose‐dependent inhibition of weed germination and early growth, highlighting their potential as bioherbicides and sustainable tools for integrated weed management. Abstract BACKGROUND Increasing selection of herbicide‐resistant weed biotypes has intensified the search for alternatives to the intensive ...

Monoterpene Production in Redberry Juniper Foliage Following Fire

open access: yes, 2007
Prescribed fire is commonly used to initiate redberry juniper (Juniperus pinchotti Sudw.) suppression, and herbivory by goats presents a potentially effective mechanism to prolong the efficacy of the reclamation treatment.
