Umpolung Synthesis of Pyridyl Ethers by BiV‐Mediated O‐Arylation of Pyridones
We demonstrate that sterically‐ and electronically‐diverse pyridyl ethers can be accessed via BiV‐mediated C−O coupling of 2‐ or 4‐pyridones with arylboronic acids. Use of a bismacyclic reagent not only confers modularity on our methodology, but also results in highly regioselective O‐arylation that is unprecedented for BiV.

Divergent rhodium-catalyzed electrochemical vinylic C–H annulation of acrylamides with alkynes
α-Pyridones and α-pyrones are ubiquitous structural motifs found in natural products and components of biologically active small molecules. Here, the authors report an oxidant-free Rh-catalyzed electrochemical divergent vinylic C–H annulation of ...

A rhodium-catalyzed C4-selective C-H alkenylation of 3-carboxy-2-pyridones with styrenes has been developed. The carboxylic group at the C3 position works as the traceless directing group, and the corresponding C4-alkenylated 2-pyridones are obtained ...

Ferrocene derivatives with planar chirality and their enantioseparation by liquid‐phase techniques
Abstract In the last decade, planar chiral ferrocenes have attracted a growing interest in several fields, particularly in asymmetric catalysis, medicinal chemistry, chiroptical spectroscopy and electrochemistry. In this frame, the access to pure or enriched enantiomers of planar chiral ferrocenes has become essential, relying on the availability of ...

13C- and 1H-NMR substituent-induced chemical shifts in N(1)-(4-substituted phenyl)-3-cyano-4,6-dimethyl-2-pyridones [PDF]
The 13C- and 1H-NMR chemical shifts of thirteen N(1)-(4-substituted phenyl)-3-cyano-4,6-dimethyl-2-pyridones were measured in deuterated dimethyl sulfoxide (DMSO-d6).
