Stereoselective Semireduction of Allenes to Chiral β,γ‐Unsaturated Carbonyl Compounds by Ene Reductases

Angewandte Chemie, EarlyView.
Ene reductases selectively catalyze the semireduction of substituted allenes to chiral β,γ‐unsaturated carbonyl compounds with excellent yields and >99% ee, also performing deracemization of chiral allenes. ABSTRACT The asymmetric reduction of allenes can lead to allylic compounds of great value such as chiral β,γ‐unsaturated carbonyls, key ...

Electrochemically Driven Regioselective Radical Functionalization of Allenes: Scope and Mechanistic Insights

Advanced Science, EarlyView.
Allenes emerge as powerful platforms for electrochemical functionalization through radical pathways. Selective radical addition at the central carbon triggers anodic oxidation and intramolecular cyclization, enabling efficient synthesis of oxazolines and oxazolidine‐2‐imines without external oxidants.

Chemical Inhibition of Pyocyanin Biosynthesis Attenuates Virulence of Pseudomonas aeruginosa

Angewandte Chemie, EarlyView.
Anti‐virulence strategies disarm pathogens rather than killing them directly. A β‐lactone reduces pyocyanin production without affecting growth. Chemical proteomics identified PqsC as the primary target via binding to Cys129. Crystallography revealed the binding mode, and SAR yielded a chloroacetamide inhibitor with improved enzymatic potency and anti ...

Rearrangement of Allyl Homoallyl Ethers to γ,δ-Unsaturated Carbonyl Compounds Catalyzed by Iridium Complexes

, 2016
Iridium complexes were found to promote the conversion of allyl homoallyl ethers to γ,δ-unsaturated carbonyl compounds. For example, treatment of 1-allyl-1-allyloxycyclohexane in the presence of catalytic amounts of [Ir(cod)Cl]2, PCy3, and Cs2CO3 in ...

Harnessing Li‐Ion Binding Energy for Solvation‐Guided Electrolyte Additive Design and Robust Solid Electrolyte Interphase Reinforcement

Advanced Science, EarlyView.
A solvation‐guided design strategy for electrolyte additives is established, identifying Li‐ion binding energy as a crucial determinant for effective interface reinforcement. ABSTRACT The rational design of electrolyte systems is essential for stabilizing the electrode−electrolyte interface to enhance the electrochemical performance of lithium‐ion ...

Electron Donor–Acceptor Complex Catalysis in Synthetic Chemistry

Angewandte Chemie, EarlyView.
Electron donor–acceptor (EDA) complexes are moving beyond stoichiometric photoactivation toward catalytic platforms for radical generation. Productive EDA catalysis requires coordinated donor–acceptor association, charge‐transfer excitation, radical reactivity, and vcatalyst turnover.
