Palladium‐Catalyzed Annulations of an Anti‐Bredt Olefin

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.
We report metal‐catalyzed trappings of a [2.2.1]‐bridged bicyclic anti‐Bredt olefin (ABO). The methodology yields unusual heterocyclic products and is expected to prompt the further development of unconventional reactions, including metal‐catalyzed processes of ABOs and other strained olefins. ABSTRACT A famous class of alkene‐containing compounds that

Enhanced through‐bond energy transfer‐based bioorthogonal probe enables catalytic‐amplified and sensitive detection of microRNA‐21 for clinical lung cancer diagnosis

Smart Molecules, EarlyView.
Inverse Diels‐Alder Cycloaddition Reaction was developed for ultrasensitive miR‐21 detection. Based on the enhanced Through‐Bond Energy Transfer and catalytic amplification, it shows a detection limit of 3.58 × 10−18 M and 100 aM–100 nM linear range. It enables high‐contrast cell/tissue imaging and distinguishes lung cancer patients in serum, promising

Synthesis of Six Natural Products Enabled by Selective Hydroxylation of Orcinaldehyde‐Like Substrates With an Enzyme Library

Angewandte Chemie, Volume 138, Issue 38, 14 September 2026.
Achieving selective (sp3)C–H hydroxylation can streamline the synthesis of complex organic molecules. Biocatalysis presents an opportunity to realize this transformation, however, identifying useful enzymes that enable synthetic strategies can be a challenge due to limitations in enzyme substrate scope.

Oxaziridines: Versatile Reagents in Modern Organic Synthesis

The Chemical Record, EarlyView.
Being capable of transferring an O atom and N‐group/atom, oxaziridines are considered multitasking agents. These are employed for diverse organic transformations, such as epoxidation of olefins, α‐ and γ‐hydroxylation/amination of carbonyl compounds, oxidation of sulfides, [3+2]cycloaddition with unsaturated systems.

Nanomedicine applications in lymphoma: Advancing precision diagnostics, targeted therapeutics, and prospective developments

VIEW, EarlyView.
Lymphoma is a group of blood cancers that can appear in lymph nodes, blood, bone marrow, spleen, liver, or the central nervous system, which makes drug delivery and disease monitoring difficult. This review summarizes how nanomedicine technologies may improve targeted treatment and imaging, while carefully separating approved or guideline‐supported ...

Four‐dimensional immuno‐mechanobiomaterials: Dynamic material cues that program host response to prevent fibrosis and enable regeneration

VIEW, EarlyView.
Dynamic immuno‐mechanobiomaterials with time‐programmed mechanical adaptation orchestrate host responses through precise mechanotransduction and immune‐stromal regulation. These adaptive biomaterials minimize mechanical mismatch, attenuate the forign dy response and fibrosis, promote angiogenesis and controlled extracellular matrix remodeling, and ...

Systematic Optimization of an SLE‐DAPTAD LC–MS/MS Workflow for Simultaneous Quantification of Low‐Abundance Vitamin D3 Metabolites in Plasma

Rapid Communications in Mass Spectrometry, Volume 40, Issue 20, 30 October 2026.
ABSTRACT Rationale Liquid chromatography–tandem mass spectrometry (LC–MS/MS) analysis of vitamin D3 metabolites is analytically challenging because these compounds are structurally similar, strongly matrix‐associated, and have poor ionization efficiency.
