Development of a Catalytic Aromatic Decarboxylation Reaction

, 2016
A palladium-catalyzed aromatic decarboxylation reaction has been developed. With electron-rich aromatic acids, the reaction proceeds efficiently under fairly mild conditions in good yields.

Synthesis of 2‐Aza‐Bicyclo[4.3.0]nonane Derivatives Related to the Camporidines via Intramolecular [3+2]‐Cycloaddition

European Journal of Organic Chemistry, EarlyView.
The intramolecular nitrile oxide olefin [3 + 2]‐cycloaddition offers a reliable entry toward 2‐aza‐bicyclo[4.3.0]‐nonanes, a substructure found in several bioactive piperidine alkaloids. The required oxime precursors were prepared in non‐racemic form by Ir‐catalyzed asymmetric allylation and ring‐closing metathesis.

Gold(I)‐Mediated Reactivity of Allenes With Mesoionic Nucleophiles: A Computational Exploration

European Journal of Organic Chemistry, EarlyView.
The regioselective gold(I)‐mediated reactivity of allenes with mesoionic nucleophiles has been evaluated through computational analysis of the mechanisms involved. Instead of typical (3 + 2) pathways, sydnones and münchnones favour the formal (3 + 3) cyclizations affording substituted dihydropyridines.

Pyruvate dehydrogenase autoantibodies in autoantibody‐negative patients with seizures are associated with reduced pyruvate dehydrogenase activity

Epilepsia, EarlyView.
Abstract Objective We investigated the presence and potential functional relevance of antimitochondrial autoantibodies in patients suspicious for autoimmune encephalitis (AIE) associated with psychiatric symptoms and/or seizures, who were negative for known antineuronal autoantibodies.

Characterization of Cantaloupe, Grape, Pumpkin, and Tomato Seed Oils From Xinjiang: Oxidative Stability, Volatile‐Compound Analysis, and Sensory Evaluation

Food Chemistry International, EarlyView.
This study compares oxidative stability, fatty acid profiles, volatile compounds, and sensory attributes of four Xinjiang seed oils. Distinct aldehyde‐driven aroma patterns and compositional differences were revealed, providing a scientific basis for quality evaluation and valorization of underutilized plant seed oils in food applications.

Effects of high‐moisture extrusion processing on reducing anti‐nutritional factors and allergenicity in plant‐based materials—A mini review

Food Biomacromolecules, EarlyView.
Abstract The rising demand for plant‐based meat alternatives has had advancements in processing technologies such as extrusion to meet consumer preferences for enhanced sensory qualities and nutritional benefits. High moisture extrusion (HME), a thermo‐mechanical process employing elevated moisture levels (40%–70%), has emerged as a promising method ...
