Photochemical Ring Opening of Cyclopropyl Silyl Ethers Enables β–β Coupling, Radical‐Polar Crossover and Annulation

Angewandte Chemie, EarlyView.
A photochemical platform enables β–β coupling of cyclopropyl silyl ethers with electron‐deficient alkenes. The resulting adducts serve as entry points into annulative and radical–polar crossover pathways, providing rapid access to fused, bridged, and spirocyclic architectures, including late‐stage scaffold diversification to diterpene‐like carbocyclic ...

Nanostructured Deep Eutectic Systems in Healthcare: From Bioactive Solvents to Intelligent Biointerfaces, Wearables, and AI‐Driven Design

Advanced NanoBiomed Research, EarlyView.
Beyond the green solvent paradigm, this review redefines Deep Eutectic Systems (DES) as programmable supramolecular nanoassemblies. We survey their biomedical convergence: stabilizing thermolabile mRNA to enable cold chain‐free logistics, reshaping transdermal microneedle delivery, enabling long‐term wearables via eutectogels, and utilizing Generative ...

Structural Control of Dual Emission in Coumarin Fluorophores for Visualizing Protein Droplet Maturation

Angewandte Chemie, EarlyView.
A coumarin‐based dual‐emission fluorophore was designed to visualize the maturation of protein liquid droplets. Upon covalent conjugation to droplet‐forming proteins, ratiometric fluorescence imaging allowed real time monitoring of droplet maturation. This probe is applicable to the analysis of droplet formation and maturation mechanisms, as well as to

Solvatochromism in Solvent Mixtures: A Practical Solution for a Complex Problem

Liquids
Many reactions are carried out in solvent mixtures, mainly because of practical reasons. For example, E2 eliminations are favored over SN2 substitutions in aqueous organic solvents because the bases are desolvated.

Cellulose swelling by aprotic and protic solvents: What are the similarities and differences? [PDF]

, 2008
The swelling of microcrystalline, native and mercerized cotton and eucalyptus celluloses by 16 aprotic solvents was investigated. The number of moles of solvent/anhydroglucose unit, nSw, correlates well with solvent molar volume, basicity and dipolarity ...

CO2 as a Redox Shuttle Enables Photocatalytic Dehydrogenative Decarbonylation of Biomass‐Derived Alcohols to Light Alkanes

Angewandte Chemie, EarlyView.
A heterogeneous photocatalytic system has been developed that enables the dehydrogenative decarbonylation of primary alcohols under visible light using highly dispersed oxidic iron sites supported on aryl‐modified graphitic carbon nitride (Fe@f–gC3N4).
