Advances in organic UV filters for sunscreens over the past decade

Photochemistry and Photobiology, EarlyView.
Highlighted organic UV filter frameworks that have been described for sunscreens over the past decade divided into three groups: derivatives of or inspired by approved organic UV filters, natural product‐based compounds, and miscellaneous. Abstract Ultraviolet (UV) radiation is a major environmental factor in photoaging, erythema, and skin cancer ...

One‐Pot Amidation/C─H Halogenation by an Efficient Electrochemical Cascade

Angewandte Chemie, Volume 138, Issue 19, 4 May 2026.
A sustainable electrochemical cascade enables the one‐pot synthesis of regioselectively halogenated N‐aryl amides from readily available amines and acyl halides under mild conditions. The method merges amidation and C─H halogenation in a single operational step, delivering broad substrate scope, high selectivity, and scalability, and provides an ...

Exploring 6‐Hydroxy‐3‐Aryl/Heteroarylcoumarins as Promising Candidates Against Trypanosoma cruzi

ChemMedChem, Volume 21, Issue 9, 14 May 2026.
New therapies are urgently needed for Chagas disease, and screening of 6‐hydroxy‐3‐aryl/heteroarylcoumarin derivatives identified highly selective compounds with potent activity against T. cruzi. In particular, derivative 1f showed submicromolar trypomastigote potency, dual‐stage activity, and inhibition of amastigote‐to‐trypomastigote differentiation,

Merging Micellar Catalysis and C–H Activation: Silver‐Free Direct Arylation of Fluoroarenes in Water

ChemSusChem, Volume 19, Issue 9, 14 May 2026.
We have developed the first silver‐free protocol for a palladium‐catalyzed direct arylation in water under micellar conditions enabling the coupling of diverse pyridine and fluoroarene derivatives. This method combines the sustainability of aqueous media with the efficiency of C–H activation, obviating the need for organic co‐solvents or stoichiometric

Functionalized Diaryliodonium Salts with N‐Reactive Amides: Versatile Reactivity for Constructing Benzo‐Fused Nitrogen Heterocycles

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
A practical one‐pot strategy for the synthesis of ortho‐amide‐functionalized TMP‐iodonium(III) salts has been developed. These iodonium salts exhibited distinct reactivities toward N‐, O‐, and S‐nucleophiles, facilitating arylocyclization and producing a variety of benzo‐fused heterocycles under mild conditions.

Catalytic Enantioselective Synthesis of Conformationally Stable C(sp2)−C(sp3) Naphthocoumarin Atropisomers

Advanced Synthesis &Catalysis, Volume 368, Issue 9, 5 May 2026.
The enantioselective synthesis of naphthocoumarin adducts via a tandem organocatalytic 1,4‐addition/decarboxylation delivers excellent control over a newly forged stereocenter and yields configurationally stable synclinal atropisomers. The process features broad substrate scope and scalability, and its structural and mechanistic foundations are ...
