Flavin Catalysts in Organic Synthesis

Angewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Atroposelective Pd(0)‐Catalyzed Direct Intermolecular C─H Arylation of Thiazole N‐Oxides Provides Access to Heterobiaryls

Angewandte Chemie, EarlyView.
An enantioselective Pd(0)‐catalysed arylation at the C4‐position of thiazole N‐oxides directly forges the atropochiral heterobiaryl axis. A tailored point‐ and axially chiral monodentate phosphine ensures high reactivities along with a tight stereocontrol.

Cobalt‐Catalyzed [2σ+2π] Cycloaddition via Site‐Selective Capture of Bicyclobutane Diradical

Angewandte Chemie, EarlyView.
We report a Co(II)‐catalyzed strategy that combines thermal activation of bicyclo[1.1.0]butane (BCBs) with site‐selective radical capture to furnish head‐to‐head fused bicyclo[2.1.1]hexanes via [2σ+2π] cycloaddition with indoles. Detailed mechanistic studies (31P NMR, EPR, CV, and DFT) support the catalytic pathway, while phosphine‐oxide trapping and X‐

Oxygen‐Tolerant, Controlled Synthesis of Degradable and Water‐Soluble Poly(Vinyl Amide)s via Radical Ring‐Opening Copolymerization of Cyclic Dithiothreitol

Angewandte Chemie, EarlyView.
Oxygen‐tolerant photoinduced electron/energy transfer reversible addition–fragmentation chain transfer (PET‐RAFT) polymerization enables the controlled radical ring‐opening (rROP) copolymerization of cyclic dithiothreitol (cDTT) with less‐activated vinyl monomers, affording degradable polymers with predictable molecular weights, low dispersities, and ...

Metal Oxides Catalyze Formation of Dehydroamino Acids by Phosphate β‐Elimination Under Physiological Conditions

Angewandte Chemie, EarlyView.
Dehydroamino acids (DHAA) are atypical electrophilic sites that lead to crosslinked proteins in Alzheimer's disease (AD) brains. No catalyst for their formation has been known in humans. We report that metal oxides catalyze β‐elimination of phosphoserine and phosphothreonine in model peptides at pH 7.5°C and 37°C, yielding DHAAs.
