Transannular O‐Heterocyclization Reactions of Cyclododeca‐1,5,9‐triene Derivatives: A New Concept for the Preparation of Key Intermediates for Total Syntheses of Annonaceous Acetogenins

Helvetica Chimica Acta, EarlyView.
Four stereogenic centers are formed diastereoselectively in one step from a cyclic (E,E)‐1,5‐diene system using an electrophilic addition reaction. Subsequent ozonolytic cleavage of the intact Z‐double bond, followed by intramolecular nucleophilic substitution, yields an octahydroterfurandione with a threo,cis,threo configuration, an arrangement found ...

Structural design and property regulation of organic polymers for photocatalytic synthesis of H2O2

InfoScience, EarlyView.
Photocatalytic synthesis of H2O2 offers a sustainable approach. Photocatalytic efficiency depends critically on interfacial electron transfer kinetics and spatial charge separation. Herein, we systematically analyze key factors governing photogenerated carrier dynamics and propose engineered strategies to optimize performance, thereby providing design ...

Development of an Insulin‐Permeable Hydrogel Membrane Based on Photocrosslinkable Poly(2‐Alkyl‐2‐Oxazoline)s

Macromolecular Materials and Engineering, EarlyView.
Hydrogel‐based composite membranes from photocrosslinkable poly(2‐alkyl‐2‐oxazoline) layers on PET meshes are presented as an insulin‐permeable barrier in delivery platforms for potential use in wound treatment. The membrane design addresses the challenge of maintaining protein structural integrity during topical delivery through polymeric hydrogel ...

Enrichment of Hyaluronic Acid Binding Tumor Cells by Modulation of Selective Adhesion on Microgel Surfaces

Macromolecular Rapid Communications, EarlyView.
We have developed a thermoresponsive microgel system for the selective enrichment of hyaluronic acid‐binding tumor cells. By modulating the adhesion on the microgel surface via temperature changes from 37°C to 30°C, we demonstrate a novel proof‐of‐principle for separating these tumor cell from white blood cells, which has potential applications in ...
