Aryl versus Alkyl Redox-Active Diazoacetates ─ Light-Induced C–H Insertion or 1,2-Rearrangement
(American Chemical Society, 2023)
Diazo compounds with redox-active leaving groups are versatile reagents for orthogonal functionalizations, previously utilized in the Rh-catalyzed synthesis of highly substituted cyclopropanes. Photochemical activation of ...
Pyridine N-oxides as HAT reagents for photochemical C–H functionalization of electron-deficient heteroarenes
(Royal Society of Chemistry, 2022)
Pyridine N-oxides have only recently marked their presence in the photocatalysis field, mainly serving as oxypyridinium salt precursors. Herein, their unique reactivity as a hydrogen atom transfer reagent in photochemical, ...
Porphyrins as Promising Photocatalysts for Red-Light-Induced Functionalizations of Biomolecules
(American Chemical Society, 2022)
Red-light enables deeper material penetration, which is important for biological applications and has consequences for chemical synthesis. Therefore, the search for new photocatalysts that absorb in this region is crucial. ...
Site-Selective, Photocatalytic Vinylogous Amidation of Enones
(American Chemical Society, 2022)
Despite the broad interest in organic compounds possessing a γ-aminocarbonyl motif, limited strategies for their synthesis have been reported. Herein, we describe a mild and efficient method for the site-selective amidation ...
Effect of amide protoporphyrin derivatives on immune response in Apis mellifera
(Springer Nature, 2022)
The intracellular microsporidian parasite Nosema ceranae is known to compromise bee health by induction of energetic stress and downregulation of the immune system. Porphyrins are candidate therapeutic agents for controlling ...
Bioinspired Cobalt-Catalysis Enables Generation of Nucleophilic Radicals from Oxetanes
(American Chemical Society, 2022-03-25)
Oxetanes are valuable building blocks due to their well-explored propensity to undergo ring-opening reactions with nucleophiles. However, their application as precursors of radical
species is still elusive. Herein, we ...
C−C Bond Forming Reactions Enabled by Vitamin B12 - Opportunities and Challenges
(American Chemical Society, 2022)
Cobalt not only is an essential micronutrient for mammals but also marks itself as important in organic synthesis, especially in the field of catalysis. Various useful reactions, such as alkene hydroformylation, hydrogenation, ...
