Chemoselective Synthesis and Anti-Kinetoplastidal Properties of 2,6-Diaryl-4H-tetrahydro-thiopyran-4-one S-Oxides: Their Interplay in a Cascade of Redox Reactions from Diarylideneacetones

Molecules
2,6-Diaryl-4H-tetrahydro-thiopyran-4-ones and corresponding sulfoxide and sulfone derivatives were designed to lower the major toxicity of their parent anti-kinetoplatidal diarylideneacetones through a prodrug effect.

Permanent Oxidative Dipole Engineering in Quinoline COFs for Boosting Exciton Dissociation and Oxygen Activation in H2O2 Photosynthesis

Advanced Science, EarlyView.
Permanent oxidative dipole (POD) engineering overcomes the electronic uniformity of quinoline‐linked COFs. By enhancing the dipole moment to 2.08 D and lowering exciton binding energy to 20.3 meV, it constructs a robust built‐in electric field and spatially decoupled redox centers. This bypasses inherent kinetic bottlenecks, achieving a 4569 µmol g−1 h−

Aromatic Pummerer‐Promoted Stereospecific Cross‐Coupling of Thiazoles With Boronic Esters

Angewandte Chemie, EarlyView.
A lithiation–borylation–aromatic Pummerer (LiBAP) strategy enables stereospecific, C5‐selective C(sp2)–C(sp3) cross‐coupling of thiazoles with boronic esters. By using exocyclic sulfoxide activation to overcome the low nucleophilicity that frustrates SEAr‐type coupling, the method delivers enantioenriched alkylated thiazoles bearing a versatile C2 ...
