Synthesis of Tetrasubstituted Allenes via Palladium-Catalyzed Cross-Coupling of Vinyl Bromides with Diazo Compounds [PDF]
, 2019 A highly efficient palladium-catalyzed cross-coupling of 2,2-diarylvinyl bromides with diazo compounds was developed, providing a convenient approach for the synthesis of tetrasubsti-tuted allenes. Both aryl diazo carbonyl compounds and N-tosylhydrazones

Hepatology, EarlyView., 2022 Abstract Background and Aims Peroxisome proliferator‐activated receptor α (PPARα) regulates fatty acid transport and catabolism in liver. However, the role of intestinal PPARα in lipid homeostasis is largely unknown. Here, intestinal PPARα was examined for its modulation of obesity and NASH. Approach and Results Intestinal PPARα was activated and fatty

Diazo compounds in continuous flow technology [PDF]
Diazo compounds are highly reactive carbene precursors which can be used to generate molecular complexity rapidly. However, diazo compounds are highly energetic and dangerous compounds and therefore, their use in large-scale applications remains rare ...

Quantification of the electrophilic reactivities of nitroalkenes [PDF]
, 2012 While a large variety of nucleophiles (N and sN) have been characterized according to eq 1.3, the number of E parameters for electrophiles, and specifically for different classes of Michael acceptors remains relatively small.

Cobalt‐Catalyzed C─N Bond Formation via Metal‐Hydride Hydrogen Atom Transfer (MHAT)
Angewandte Chemie, EarlyView.Cobalt‐catalyzed metal‐hydride hydrogen atom transfer (Co‐MHAT) converts simple alkenes into C─N bonds under mild, near‐neutral conditions. A shared Co─H‐initiated radical/organocobalt intermediate is channeled into radical trapping, radical‐polar crossover, or radical ligand transfer, unifying hydroamination, hydroazidation, hydroamidation, and remote

Iodine-catalyzed diazo activation to access radical reactivity
Nature Communications, 2018 Radical reactivity of diazo compounds, useful organic building blocks, is yet underexplored. Here, the authors report an iodine-catalyzed radical activation of diazo compounds affording a variety of substituted cyclopropanes, pyrroles and epoxides under ...

Electrosynthesis of stabilized diazo compounds from hydrazones [PDF]
, 2022 An electrochemical synthesis of diazo compounds from hydrazones in yields as high as 99% was performed. This method was elaborated as a useful synthetic method and demonstrated on various diazo compounds (24 examples). Apart from exhibiting an efficiency

Angewandte Chemie, EarlyView.Catalyst‐controlled nitrene transfer unlocks divergent reactivity of bicyclo[1.1.0]butanes. Rhodium catalysis promotes selective strain‐release amination to access cyclobutene and cyclobutane amino‐acid scaffolds, whereas visible‐light photocatalysis redirects nitrene reactivity toward double amination and skeletal remodeling, providing a complementary
