Pyrrolizine- and Indolizine-Derived Spirooxindoles: Synthesis, Antibacterial Activity and Inverse Docking Analysis

Chemistry
Spirooxindoles are a family of heterocyclic compounds which bear the oxindole nucleus in their structures, which have a considerable pharmaceutical potential and which have been linked to various drugs for the treatment of diverse diseases. In this work,

Low‐Carbon Poly(3‐vinyl‐N‐methylphenothiazine) Electrode Formulation Using PEDOT:PSS (poly(3,4‐ethylenedioxythiophene):poly(styrene sulfonate)) for Lithium‐Based Energy Storage

Advanced Energy and Sustainability Research, EarlyView.
Organic electrode materials typically suffer from low electronic conductivity, requiring large amounts of carbon additives. Herein, a conducting polymer, PEDOT:PSS, is introduced as a partial replacement for carbon black, reducing the carbon content to 15 wt%.

Halide Bond Assisted Double Desymmetrization of Meso‐Dicarboxylic Acids with Symmetrical Olefins via Asymmetric Halogenation

Angewandte Chemie, EarlyView.
This work demonstrates a double desymmetrization of meso‐dicarboxylic acids with symmetrical olefins, constructing complex chiral lactones with six stereocenters in one step. Unexpectedly, the halide bond was found to be crucial in achieving high stereoselectivity.

Development and systematic evaluation of triamine‐based functional deep eutectic solvents for efficient CO2 capture

AIChE Journal, EarlyView.
Abstract The development of advanced absorbents for effectively capturing carbon dioxide is crucial in mitigating greenhouse gas emissions. This study introduced a series of deep eutectic solvents (DESs) for CO2 capture and identified the most promising DESs with the stepwise screening method based on their absorption capacity, absorption rate, thermal

Photoinduced Ring‐Opening Polymerization of N‐Carboxyanhydrides for the Preparation of Cross‐Linked Polypeptide Gels

Angewandte Chemie, EarlyView.
We employ a photochemical approach for ring‐opening polymerization (ROP) of α‐amino acid N‐carboxyanhydride (NCA) monomers to prepare covalently cross‐linked synthetic polypeptide gels using a photobase and light, which offers significant advantages in the synthesis of polypeptides and holds great potential for applications requiring spatial and ...

Photothermal Conversion Promotes Challenging SNAr for Facile C─N Bond Formation

Angewandte Chemie, EarlyView.
Photothermal conversion enables facile aromatic C─N bond formation via red light irradiation. A variety of inter‐ and intramolecular SNAr transformations are achieved under mild, schematically simple conditions. Additionally, a thermally promoted halogen exchange mechanism provides access to aryl bromides, chlorides, and fluorides – making this ...

Boosting the Nucleophilicity of the Diphenylphosphide Anion with Crown Ether Supported Heavy Alkali Metals to Facilitate Highly Efficient Catalytic Alkene Isomerisation

Angewandte Chemie, EarlyView.
Here, we report a breakthrough study in catalytic alkene isomerisation using crown ether‐supported alkali metal phosphides in which the activity increases sequentially and significantly as Group One is descended with Cs(18‐crown‐6)PPh2 (1Cs) performing best.

Double E─H Bond Activation of Ammonia and Water by Cyclic Gallaphosphene L(OCP)GaPGaL

Angewandte Chemie, EarlyView.
Cyclic gallaphosphene 1 undergoes a twofold E─H bond activation with ammonia and water via a beneficial interplay between the polar “GaPGa” unit and the electrophilic nature of the C center in the bridging PCO unit, yielding six‐membered heterocycles 2 and 3, in which both nucleophilic phosphorus atoms are protonated.
