Radical‐Polar Crossover Bicyclization Enables a Modular Synthesis of Saturated Bicyclic Amines

Advanced Science, EarlyView.
Herein, we report the successful realization of a radical‐polar crossover bicyclization reaction from easily available cyclopropylamines and substituted alkenes through photoredox catalysis. This approach introduces an innovative methodology for the de novo synthesis of a diverse collection of 4/5‐, 5/5‐, 6/5‐,7/5‐ and 5/6‐fused saturated bicyclic ...

Electrochemical Functionalization of Graphene‐on‐Cu(111): Reactivity, Onset Potentials, and Mechanistic Insights

Advanced Science, EarlyView.
The electrochemical reactivity of graphene‐on‐Cu(111) with various phenyl and alkyl iodides showed different onset potentials. Differential pulse voltammetry (DPV) and density functional theory (DFT) calculations are used to elucidate the differences in onset potentials for phenyl iodides with different substituents.

Hydrocyclization/Defluorination of CF3‐Substituted Acrylamides: Insights from Kinetics of Hydrogen Atom Transfer

Advanced Science, EarlyView.
The study develops a H•/H– transfer strategy enabling efficient hydrocyclization/defluorination of CF3‐acrylamides to synthesize Seletracetam derivatives with gem‐difluoroalkenes. Mechanistic studies reveal distinct pathways: the NiII‐H/PhSiH3 system operates through a hydrogen atom transfer process, while the 1,4‐Michael addition of H– appears to be ...

Targeted Dual‐Responsive Liposomes Co‐Deliver Jolkinolide B and Ce6 to Synergistically Enhance the Photodynamic/Immunotherapy Efficacy in Gastric Cancer through the PANoptosis Pathway

Advanced Science, EarlyView.
Schematic model of CJP–TiN liposomes for gastric cancer (GC) treatment. Internalizing RGD peptide (iRGD) targets tumor cells, while Chlorin e6 (Ce6) generates reactive oxygen species (ROS). Jolkinolide B (JB) activates the PANoptosis pathway via caspase‐8, enhancing GC cell death and immune response, transforming “cold tumors” into “hot tumors” by ...
