Bottlebrush Polyolefin Sulfones as Triggerable and Degradable Pressure‐Sensitive Adhesives

Angewandte Chemie, EarlyView.
A grafting‐through alternating copolymerization strategy yields poly(norbornene sulfone) bottlebrush polymers with high molar mass. These materials function as additive‐free pressure‐sensitive adhesives. The incorporation of cleavable sulfone units enables rapid breakdown under mild alkaline conditions, providing a pathway toward sustainable, high ...

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 ...

Generative and Experimental Validation of High Refractive Index Polymers via Domain Knowledge Approach with Small Data

Advanced Intelligent Discovery, EarlyView.
This research demonstrates that the combination of domain knowledge–based multiple regression, multi‐objective Bayesian optimization, and generative models is a suitable prediction tool for candidates of high refractive index polymers, even with the constraints in the model trained on limited data. The experimental validation can reproduce the proposed

Borylcyclopropanes: Synthetic Strategies and Applications

Angewandte Chemie, EarlyView.
Borylcyclopropanes (cyclopropanes bearing a boron substituent) sit at the intersection of two privileged frameworks in synthesis. This review provides the first exhaustive survey of their chemistry, spanning metal–carbene, nucleophilic cyclization, radical, hydroboration, and C─H activation routes, and documenting applications in medicinal chemistry ...

Synthese Unkonventioneller α‐Polyhalogenierter Amine Durch Hydroaminoalkylierung

Angewandte Chemie, EarlyView.
Es wird ein redox‐neutrales Verfahren beschrieben, bei dem Alkene und Alkine unter Verwendung stabiler Hemiaminal‐Reagenzien in α‐Polyhalogenmethylamine umgewandelt werden. Dieser Ansatz ermöglicht den Zugang zu α‐CF3‐, α‐CF2H‐, α‐CF2Cl‐, und α‐CFClH‐Aminen und besticht durch ein breites Substratspektrum, eine hohe Toleranz gegenüber funktionellen ...

Stereodivergent C‐(Hetero)Aryl Glycosylation by Nickel‐Catalyzed Redox‐Neutral Cross‐Coupling of Glycosyl Sulfonyl Hydrazides

Angewandte Chemie, EarlyView.
A nickel‐catalyzed C–C cross‐coupling protocol employing bench‐stable glycosyl sulfonyl hydrazides as practical glycosyl radical precursors is reported. A variety of (hetero)aryl iodides underwent cross‐coupling under redox‐neutral conditions to afford structurally diverse unprotected C‐(hetero)aryl glycosides.
