Oxidant‐Expedited Synthesis of H‐Phosphonates

European Journal of Organic Chemistry, EarlyView.
An exceptionally mild method for synthesis of alkyl and aryl H‐phosphonates from phosphites is reported, requiring only water and O2 (including air) as reagents. Mechanistic experiments indicate that the role of O2 (and other oxidants) in the transformation is to promote a radical mechanism, and that H2O functions to provide both the hydrogen and the ...

Synthesis of Cysteine–Fluorophore Conjugates by Visible‐Light‐Promoted Thiol–Ene Coupling Using Organic Photocatalysts

European Journal of Organic Chemistry, EarlyView.
Cysteine–fluorophore conjugates were efficiently prepared through a visible‐light‐driven thiol–ene approach employing solely organic photocatalysts. The reaction proceeds under mild, metal‐free conditions. The fluorophore scope includes mono‐ and dialkene‐functionalized naphthalene, naphthalimide, and aromatic diimide derivatives.

Diagnosis of bacteraemia in neonatal foals using 16S rRNA high‐throughput sequencing

Equine Veterinary Journal, EarlyView.
Abstract Background Sepsis is an important cause of morbidity and mortality in foals. Early diagnosis can improve outcome but is complicated by non‐specific clinical signs and delayed confirmation of infection via blood culture. Molecular assays represent a rapid and more sensitive alternative.

Mining Oral Probiotics Based on Their Pathogen Inhibition and Deodorization Roles

Food Bioengineering, EarlyView.
A promising oral probiotic strain Streptococcus salivarius MY‐6 stood out from 41 candidate lactic acid bacteria through the high‐throughput strategy based on its inhibitions of the growth and biofilm formation of the main oral pathogens Fusobacterium nucleatum and Porphyromonas gingivalis, as well as its elimination of oral malodor‐associated ...

Bridging Flavour and Fragrance: A Behaviour‐Based Olfactory Pyramid for Whisky Maturation Inspired by Perfumery Principles

Flavour and Fragrance Journal, EarlyView.
This framework transposes the perfumery olfactory pyramid to whisky maturation by sequencing aromas into top, heart, and base notes according to their temporal persistence. Using Log P as a behaviour‐based classification axis and oak macromolecules as natural fixative analogues, it proposes a behaviour‐based aromatic wheel bridging flavour chemistry ...

Tracking Base Note Persistence in Fragrances by Time‐Resolved Analysis: Revealing Ingredient Contributions

Flavour and Fragrance Journal, EarlyView.
A validated dynamic headspace–thermal desorption–GC method was developed to measure the substantivity of synthetic musks over time. The method enables objective assessment of fragrance persistence and highlights the contribution of fragrance long‐lasting technologies.

Monitoring and Mitigation Strategies for Hazardous Compounds in Chinese Rice Wine (Huangjiu): A Comprehensive Review

Food Safety and Health, EarlyView.
This review elucidates the formation pathways and detection technologies for ethyl carbamate, biogenic amines, and higher alcohols in Huangjiu. It concludes that integrated control frameworks are essential to decouple safety risks from the metabolic processes responsible for flavor development.
