Cobalt(III)-Catalyzed Regioselective C6 Olefination of 2-Pyridones Using Alkynes: Olefination/Directing Group Migration and Olefination

Organic Letters, 2021
Co(III)-catalyzed highly regio- and stereoselective direct C6 olefination of 2-pyridones with alkynes has been developed with the assistance of chelation.

Redox‐Divergent Synthesis of Fluoroalkylated Pyridines and 2‐Pyridones through Cu‐Catalyzed N−O Cleavage of Oxime Acetates

Angewandte Chemie - International Edition, 2018
Cu-catalyzed redox-divergent [3+3] coupling of oxime esters with β-CF3 enones and acrylates is described. This redox-neutral coupling with enones and acrylates affords trifluoromethylated pyridines and pyridones, respectively. Under reductive conditions,

Alkynyl Triazenes as Fluoroalkyne Surrogates: Regioselective Access to 4-Fluoro-2-pyridones by a Rh(III)-Catalyzed C–H Activation–Lossen Rearrangement–Wallach Reaction

ACS Catalysis, 2020
Fluorinated pyridones are an important scaffold displaying relevant biological activities. Efficient assembly strategies of pyridones are transition metal-catalyzed C–H annulations with alkynes.

Transition‐Metal‐Catalyzed Regiodivergent and Stereoselective Access to Branched and Linear Allylated 4‐Pyridones

Chemistry - A European Journal, 2017
A regiodivergent and stereoselective transition-metal-catalyzed addition of 4-pyridones to allenes furnishing N-allylated pyridones is reported. Employing a commercially available chiral rhodium catalyst enabled enantioselective branched-selective ...
