FeIII‐Mediated Synthesis of Azaspirodienones via Ipso‐Radical Cyclization of Ugi–4CR Adducts

European Journal of Organic Chemistry, EarlyView.
An efficient two‐step protocol for the synthesis of azaspirodienones via Fe‐mediated ipso‐radical cyclization of Ugi adducts has been developed. This methodology provides rapid access to these privileged spirocyclic architectures under mild conditions, offering a practical and versatile approach to generating structurally complex molecules with ...

Abnormal functional connectivity patterns in temporal lobe epilepsy—An international ENIGMA‐epilepsy study

Epilepsia Open, EarlyView.
Abstract Objectives Temporal lobe epilepsy (TLE) impacts multiple brain networks. Aberrant functional connectivity has been demonstrated in resting‐state networks (RSNs) that mediate higher brain functions in TLE. This study aimed to identify the reproducible patterns of altered functional connectivity in TLE in a large, international cohort through ...

The effect of calcium and magnesium on the aggregation of a purple phototrophic bacteria mixed consortium

Journal of Chemical Technology &Biotechnology, EarlyView.
Abstract BACKGROUND An essential aspect of applying Purple Phototrophic Bacteria (PPB) technology for wastewater treatment is the biomass separation from the aqueous phase. Ca2+ and Mg2+ have been used to enhance the aggregation of different biological matrices. In this paper, the effect of Ca2+ and Mg2+ on the aggregation of a mixed culture of PPB was

A pd‐Catalyzed Three‐Component Approach for the Synthesis of Monomeric and Dimeric Tetrahydro‐4H‐Furo[2,3‐b]Chromene Steroids

Journal of Heterocyclic Chemistry, EarlyView.
The three‐component reaction of a steroid bearing a dihydrofuran ring, with methyl orthoformate and salicylaldehyde produced chromanketals. ABSTRACT The three‐component reaction of a steroid bearing a dihydrofuran ring, with methyl orthoformate and salicylaldehyde produced chromanketals through a [4 + 2] inverse electron demand cycloaddition ...

Management and incipient domestication of Chamaedorea tepejilote in agroforestry systems in Mexico

PLANTS, PEOPLE, PLANET, EarlyView.
Native wild plants are key elements in addressing global biodiversity loss and supporting sustainable food systems. We investigated how rural communities in Mexico manage Chamaedorea tepejilote, a wild palm with edible male inflorescences, by combining ethnobotanical, genetic, morphological and ecological approaches.

The European honey buzzard (Pernis apivorus) as an ally for the control of the invasive yellow‐legged hornet (Vespa velutina nigrithorax)

Pest Management Science, Volume 81, Issue 4, Page 2237-2247, April 2025.
The predatory effect of the honey‐buzzard affects the reproductive performance of Asian‐hornet colonies, decreasing the density of workers over distance and time. The foraging distances of the honey‐buzzard concentrates within the first 2000 m from nest, which supports the results observed.
