Nitromethane conjugate addition to 2-[(1E,3E)-4-arylbuta-1,3-dien-1-yl]-4Hchromen- 4-ones [PDF]

, 2017
Chromone are a group of oxygen-containing heterocycles, which are often associated to important biological activities.1 Chromone derivatives are also seen as interesting scaffolds to input further functionalizations,2 most of them through chemical ...

Polymer‐in‐Cage Strategy for Pore Tuning of High‐Aspect Ratio ZIF Nanoplate: Toward Sub‐Micrometer‐Thick Large Area CO2 Separation Membranes

Advanced Science, EarlyView.
A “polymer‐in‐cage” strategy transforms a zinc‐acrylate copolymer into an active pore‐modulating agent for ZIF‐8 nanoplates. The polymer actively tunes the MOF's pore structure by anchoring within its windows, while the nanoplates create tortuous pathways.

CRISPR‐Cas9‐Loaded Theranostic Liposomes for Enhancing Radiosensitization of Prostate Cancer through POLD4 Gene Editing under Real‐Time MRI Monitoring

Advanced Science, EarlyView.
This study identifies POLD4 as a potential prostate cancer radiosensitization target through transcriptome sequencing. By encapsulating POLD4‐targeted CRISPR/Cas9 plasmids and USPIONs in cationic liposomes, an MRI‐monitored gene‐editing platform is established.

Desymmetrization of Malonic Monoesters and Malonic Acids via Enantioselective Catalytic C(sp3)─H Oxidation

Angewandte Chemie, EarlyView.
Manganese‐catalyzed enantioselective C(sp3)─H lactonization with hydrogen peroxide enables the direct desymmetrization of malonic monoesters and malonic acids, providing highly enantioenriched γ‐ and δ‐lactones (up to >99% ee) ABSTRACT Malonate derivatives are readily available starting materials widely employed in the synthesis of bioactive compounds.

Intelligent Soft Opto‐Magnetic Robot for Minimally Invasive Interventional Therapy

Advanced Science, EarlyView.
An intelligent soft opto‐magnetic (iSOM) robot is developed that integrates remote magnetic actuation, skin‐mimic tactile perception, and photothermal ablation in a near‐millimeter‐scale design. It enables precise intraluminal navigation and localized ablation while providing real‐time optical feedback to support safe and accurate minimally invasive ...

A Mechanochemical Kolbe–Schmitt Reaction: Catechol Carboxylation Provides Building Blocks for Renewable Plasticizers

Angewandte Chemie, EarlyView.
A mechanochemical Kolbe–Schmitt reaction of disodium catecholate enables the synthesis of mono‐ and dicarboxylated catechols at low temperature and CO2 pressure. Directly derivatizing the resulting carboxylic acid and phenolic moieties in the obtained mixture provides plasticizer blends with efficiencies competitive to commercial benchmarks.

Enhancing Chemical Stability and Molecular Selectivity of Porous Organic Cages via Core–Shell Polymer Coating

Advanced Science, EarlyView.
This study presents an interfacial method to fabricate POC@polymer core–shell nanostructures combining cage porosity with polymer robustness. Through chiral self‐assembly and non‐solvent‐induced surface polymerisation, uniform ∼20 nm polymer‐coated particles are produced.

Rapid and Stereoselective Ring‐Opening Polymerization of rac‐Lactide Enabled by a Chiral Cyclopropenimine–Thiourea Catalyst

Angewandte Chemie, EarlyView.
Chiral cyclopropenimine–thiourea organocatalysts enabled both high reactivity and precise stereocontrol in the ring‐opening polymerization of rac‐lactide. The bifunctional system exhibited a TOF up to 1,710 h−1 with Pm = 0.90 at 25°C, and achieved Pm = 0.99 at −78°C while maintaining a TOF of 16.3 h−1.
