Synthesis of γ,δ-Unsaturated Glycolic Acids via Sequenced Brook and Ireland−Claisen Rearrangements [PDF]

, 2010
Organozinc, magnesium, and lithium nucleophiles initiate a Brook/Ireland-Claisen rearrangement sequence of allylic silyl glyoxylates resulting in formation of γ,δ-unsaturated α-silyloxy ...

Constitutive Metabolomic Profiles Linked to Seasonal Climate Niche Adaptation and Resilience to Black Rot in Cabbage

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants are dynamic chemical factories that produce diverse specialised metabolites essential for growth, defence, and environmental adaptation. Metabolomes, shaped by genetic architecture, enable plants to respond to abiotic and biotic pressures, including temperature fluctuations.

Three-Component Glycolate Michael Reactions of Enolates, Silyl Glyoxylates, and α,β-Enones

, 2016
Silyl glyoxylates react with enolates and enones to afford either glycolate aldol or Michael adducts. Product identity is controlled by the countercation associated with the enolate. Reformatsky nucleophiles in the presence of additional Zn­(OTf)2 result

Aqueous Photochemistry of Glyoxylic Acid

The Journal of Physical Chemistry A, 2016
Aerosols affect climate change, the energy balance of the atmosphere, and public health due to their variable chemical composition, size, and shape. While the formation of secondary organic aerosols (SOA) from gas phase precursors is relatively well understood, studying aqueous chemical reactions contributing to the total SOA budget is the current ...

Mitochondrial Respiratory Metabolism in Salt‐Stressed Barley (Hordeum vulgare): TCA Cycle Activation With Limited GABA Shunt Engagement

Plant, Cell &Environment, EarlyView.
ABSTRACT Plants maintain energy balance under salinity stress through increased respiration and energy use, processes also associated with reactive oxygen species generation. Although respiration imposes a high energy cost, mitochondrial respiration and the tricarboxylic acid (TCA) cycle activity are vital for ATP production and for providing electron ...

Three-Component Glycolate Michael Reactions of Enolates, Silyl Glyoxylates, and α,β-Enones

, 2015
Silyl glyoxylates react with enolates and enones to afford either glycolate aldol or Michael adducts. Product identity is controlled by the countercation associated with the enolate.

Maternal protein restriction programs the ageing kidney: Proteomic signatures of early‐life origin renal and metabolic dysfunction

The Journal of Physiology, EarlyView.
Abstract figure legend Maternal protein restriction (MPR) induced persistent renal histopathological alterations accompanied by elevated serum creatinine levels. Nephron‐segment proteomic analysis revealed region‐specific molecular dysregulation affecting Bowman's capsule (PARK7, oxidative stress sensor; MSN, cytoskeletal organization), the proximal ...

Citrus depressa peel extract and its polymethoxyflavones mitigate acetaminophen‐induced chronic liver injury in mice through antioxidant activation, epigenetic regulation, and gut microbiota modulation

Journal of the Science of Food and Agriculture, Volume 106, Issue 13, Page 7629-7642, October 2026.
Abstract BACKGROUND Preventing chronic liver damage is essential for maintaining overall health and reducing the risk of serious liver diseases. Acetaminophen (APAP) overdose can lead to severe liver damage due to oxidative stress, and citrus fruits are rich in bioactive compounds that may have health benefits.

Remote Stereoinduction in the Acylation of Fully Substituted Enolates: Tandem Reformatsky/Quaternary Claisen Condensations of Silyl Glyoxylates and β-Lactones

, 2016
Reformatsky reagents react sequentially with silyl glyoxylates and β-lactones to give highly functionalized Claisen condensation products. A heretofore undocumented instance of stereochemical 1,4-induction results in efficient transmission of β-lactone ...

Resource Recovery From Food Processing Wastewater Through Microalgae‐Driven Carbon Chain Rearrangement

GCB Bioenergy, Volume 18, Issue 10, October 2026.
Carbon chain rearrangement reframes food‐processing wastewater treatment from COD removal to controlled carbon recovery. By coupling microalgal biosynthesis with bacterial substrate transformation, algal–bacterial consortia can redirect heterogeneous wastewater carbon toward recoverable biomolecules.
