Photochemical Decatungstate‐Catalyzed Hydroacylation of Maleimides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A photocatalytic protocol to access substituted succinimides via tetra‐n‐butylammonium decatungstate photocatalysis is reported. This direct radical‐driven hydroacylation of a variety of N‐substituted maleimides shows tolerance to various aldehydes (or alkanes), affording differentially substituted succinimides in high yields. Succinimides constitute a

1,2‐Diazetidines − Structure, Synthesis, and Functionalization

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
1,2‐Diazetidines are saturated four‐membered heterocycles featuring two adjacent nitrogen atoms. Despite recent advances in their synthesis and promising potential in medicinal chemistry, the chemistry of these cyclic hydrazines remains underexplored.

1,2,6‐Thiadiazin‐4‐ones: Robust Photocatalysts for the Green Aerobic Oxidation of Sulfides to Sulfoxides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A new photocatalyst for the aerobic photochemical oxidation of sulfides to sulfoxides is described under really low catalyst loading (0.01 mol%) and methanol as the green solvent. The chemoselective oxidation of sulfides to sulfoxides is accomplished using a new family of photocatalysts, namely 1,2,6‐thiadiazin‐4‐ones. Utilizing a low catalyst loading (

Phase‐Transfer‐Catalyzed Interrupted Barton–Zard Reaction Between Electron‐Deficient Indoles and Benzophenone‐Derived Isocyanides

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
A cascade reaction under phase‐transfer conditions between 3‐nitro indoles and isocyanomethylene dibenzenes affords the construction of pyrrolo[3,4‐b]indole cores. Control experiments provide insight into moderate product yields and clarify why the reaction is not amenable to asymmetric induction. A cascade reaction enabling the construction of pyrrolo[

Unlocking the Functionalization and Reactivity of Ethylene Bridges in [2.2]Paracyclophanes: Strategies and Challenges

open access: yesEuropean Journal of Organic Chemistry, EarlyView.
Bridging the gap. Beyond deck functionalization, the ethylene bridges of [2.2]paracyclophanes offer a largely unexploited reactivity landscape. This review showcases strategies to functionalize these bridges and leverage them to build novel cyclophane architectures.

Structure and Spectroscopy of Criegee Intermediates in Gas‐ and Aqueous Environments

open access: yesHelvetica Chimica Acta, EarlyView.
ABSTRACT The dynamics and spectroscopy of the small (H2COO) and large (CH3CHOO) Criegee intermediates (CIs) in the gas phase, inside/on water droplets, on amorphous solid water (ASW) and in bulk water are investigated using validated energy functions.

Engineered extracellular vesicles for precision renal therapy: Bioengineering strategies and clinical translation

open access: yesInterdisciplinary Medicine, EarlyView.
Engineered extracellular vesicles (EVs) offer a versatile platform for kidney‐targeted therapy. This review summarizes bioengineering strategies, including cargo loading, surface modification, biomimetic fabrication, and biomaterial integration. We highlight translational challenges and propose future solutions to accelerate the clinical application of

A personal 360° view of applications of ‘biomimetic’ molecular recognition

open access: yesJournal of Chemical Technology &Biotechnology, EarlyView.
Abstract Molecular recognition between biological molecules has formed the basis for innumerable applications in biotechnology for the last seven decades or so. Techniques such as affinity chromatography, solid‐phase and aqueous two‐phase extraction, affinity precipitation, biomimetic catalytic systems, biosensors and molecular imprinting all exploit ...

Diacetylene‐Functionalized Glycan Mimetics for Receptor‐Mediated Cluster Imprinting in Model Membranes

open access: yesMacromolecular Rapid Communications, EarlyView.
Diacetylene‐containing glycan mimetics cluster upon selective lectin binding in GUVs. Subsequent irradiation leads to the formation of fluorescent polymer clusters, while non‐clustered glycan mimetics remain unaffected in the membrane. ABSTRACT The glycocalyx, a dense layer of glycoproteins and glycolipids on eukaryotic cells, is essential for cellular
