Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

The Chemical Record, EarlyView.
This review provides a comprehensive and critical analysis of low‐impact synthetic methodologies reported in the last 8 years (2018–2026) for the construction of benzopyran‐derived scaffolds, such as coumarins, flavones, chromones, chromenes, and chromanes. The benzopyran scaffold is a versatile family of heterocycles found in a wide range of bioactive

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.

Effect of diphenyl diselenide on the development of experimental autoimmune encephalomyelitis

Neurochemistry International, 2011
Experimental autoimmune encephalomyelitis (EAE) is a T cell-mediated inflammatory and demyelinating disease of the central nervous system with clinical and pathological similarities with multiple sclerosis. The oxidative stress is one of the major mediators of demyelination and axonal damage in both, multiple sclerosis and EAE.

The ¹²⁵Te Chemical Shift of Diphenyl Ditelluride: Chasing Conformers over a Flat Energy Surface

Molecules, 2019
The interest in diphenyl ditelluride (Ph2Te2) is related to its strict analogy to diphenyl diselenide (Ph2Se2), whose capacity to reduce organic peroxides is largely exploited in catalysis and green chemistry.

A Unified Photoredox Platform for Divergent Dual C─H/N─H Selenylation to Access N,C‐ and C,C‐Diselenides

Asian Journal of Organic Chemistry, Volume 15, Issue 8, August 2026.
We report a visible‐light photoredox‐catalyzed strategy for the divergent dual selenylation of inert C─H and N─H bonds. Using a single catalytic system with Ru(bpy)3Cl2·6H2O and diselenides, arylamines and indoles are selectively converted to distinct N,C‐ or C,C‐disubstituted organoselenides, respectively. ABSTRACT We report a visible‐light photoredox‐

Synthesis of 3‐Chalcogenyl‐benzo[b]Chalcogenophenes via Chalcogenation/Cyclization of Alkynes Promoted by Selectfluor

Asian Journal of Organic Chemistry, Volume 15, Issue 8, August 2026.
A simple, mild, and safe electrophilic chalcogenocyclization reaction of a diverse array of alkynyl chalcogenoanisoles is depicted. The reactions are mediated by Selectfluor, as a stable, easy‐to‐handle, nontoxic, and safe oxidizing agent. Several 3‐chalcogenyl‐benzo[b]chalcogenophenes were obtained in moderate to excellent yields.
