Advances in Unconventional and Sustainable Synthetic Approaches to Benzopyran Scaffolds

open access: yesThe 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

Sulfur‐ and Selenium‐Decorated Coumarins: Synthetic Strategies Involving Cyclization and Late‐Stage Functionalization

open access: yesThe Chemical Record, EarlyView.
Two decades of synthetic strategies for sulfur‐, selenium‐decorated coumarins are critically surveyed through 44 literature reports, with particular emphasis on derivatives functionalized at the C‐3 and C‐4 positions. This review reports the direct construction of the coumarin framework through cyclization processes and late‐stage functionalization of ...

Flavin Catalysts in Organic Synthesis

open access: yesAngewandte Chemie, Volume 138, Issue 42, 12 October 2026.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Response of Remote Tropical West Pacific Islands to Climate Variability: A Multiproxy Record From T‐Lake, Palau, Spanning the Early Holocene to Present

open access: yesArchaeometry, EarlyView.
ABSTRACT Lake sediments are natural archives of past environmental dynamics and how these systems have responded to past climate variability. Sediment geochemistry, governed by local geology and climate processes, is unique to each lake‐catchment and geochemical proxies must be validated for each study site.

Scaling‐Up Vanadium Redox Flow Batteries: From Lab‐Scale Flow Cells to Application Stacks

open access: yesAdvanced Chemical Engineering, Volume 1, Issue 2, December 2026.
The transition of vanadium redox flow batteries (VRFBs) from laboratory cells to practical stacks encounters integrated limitations in key components. This review emphasizes component‐level optimization and engineering considerations for electrodes, electrolytes, membranes, and flow fields. Critical trade‐offs among different metrics across large‐scale

Photochemical Reaction Discovery Enabled by the Dynamic Speciation of Copper Complexes

open access: yesAngewandte Chemie, Volume 138, Issue 41, 5 October 2026.
A strategy for accelerated photochemical reaction discovery is reported that harnesses the dynamic speciation of copper complexes, driven by their labile metal–ligand bonds. This platform simplifies reaction screening by combining an earth‐abundant copper(II) salt with commercially available ligands, which reversibly generate multiple catalytic species
