Asymmetric α‐Alkylation With Activated and Unactivated Electrophiles by a Highly Productive and Recyclable Lewis Acid/Imidazolium Catalyst

Angewandte Chemie International Edition, Volume 65, Issue 27, 1 July 2026.
An air‐stable, easily prepared, bifunctional Cu(II)/imidazolium complex enables highly enantioselective α‐alkylation of 1,3‐dicarbonyls with outstanding productivity (TON up to 1740). Highlights include broad electrophile scope spanning π‐activated and nonactivated reagents, stereo‐retentive allylation, simple catalyst synthesis, and efficient catalyst

Multi‐Targeting Ligands as Prospective Therapeutics for Alzheimer's Disease, a Prevalent Neurodegenerative Disorder: Mechanistic Insights, Emerging Targets and Drug Discovery Campaigns

Medicinal Research Reviews, Volume 46, Issue 4, Page 1173-1229, July 2026.
ABSTRACT Alzheimer's disease (AD) is a debilitating neurodegenerative condition characterized by progressive cognitive impairment, memory deterioration, and neuronal dysfunction. Its complex pathophysiology involves multiple interlinked processes, including amyloid‐β (Aβ) aggregation, tau hyperphosphorylation, oxidative stress, neuroinflammation ...

High‐Energy‐Density Redox Flow Batteries: Mechanisms, Design Strategies, and Recent Progress

Chemistry – A European Journal, Volume 32, Issue 24, 23 June 2026.
ABSTRACT The inherent intermittency of energy sources such as solar and wind power hinders the transition to renewable energy, necessitating advanced energy storage solutions. Enhancing energy density is crucial for lowering system costs and enabling large‐scale deployment.

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

European Journal of Organic Chemistry, Volume 29, Issue 24, 23 June 2026.
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.

Site‐Selective Functionalization of Cysteine Units in Peptides Through Meerwein Arylation Reactions Under Mild Conditions

Advanced Synthesis &Catalysis, Volume 368, Issue 12, 17 June 2026.
α‐Methylstyrenes are known as highly efficient scavengers for aryl radicals. Herein, a bifunctional reagent is introduced that merges a 2‐bromoacyl moiety for thiol coupling with a styrene unit for subsequent radical functionalization. The sequential transformations proceed under mild conditions, enabling selective cysteine modification in peptidic ...
