ChemInform Abstract: Concise Entries to 4‐Halo‐2‐pyridones and 3‐Bromo‐4‐halo‐2‐pyridones. [PDF]

open access: yesChemInform, 2015
Methods for the synthesis of both simple 4-halo-2-pyridones and more functionalized 3,4-di- and (3,4,5-tri)-halo-2-pyridones are described that are based on a combination of Sandmeyer and regioselective (copper-mediated) halogenation, with a 2-chloro or a 2-benzyl­oxy moiety serving as a masked 2-pyridone.

Ligand‐Enabled Nondirected and Regioselective Arylation of Internal Alkenes with Simple Arenes

open access: yesAngewandte Chemie, Volume 137, Issue 16, April 11, 2025.
A regioselective insertion of (hetero) aryl groups into the C−C double bond of unactivated internal alkenes by nondirected arene‐C(sp2)−H activation has been achieved. The design and development of a new ligand‐supported palladium catalysis, enables quick access to trisubstituted alkenes, especially E‐1,2‐diarylalkenes, from unfunctionalized simple raw

Designing Enzymatic Reactivity with an Expanded Palette

open access: yesChemBioChem, EarlyView.
Innovation in biocatalysis is rapidly increasingly the diversity of catalytic reactivity that can be mediated by enzymes, addressing a key bottleneck for their widespread adoption in industrial chemical synthesis. A key approach to this is building enzymes with unnatural catalytic components that provide an expanded palette with new possibilities for ...

6-Methyl-2-pyridone pentahydrate [PDF]

open access: yesActa Crystallographica Section E Structure Reports Online, 2004
Crystals of the title compound, C6H7NO·5H2O, were grown over a period of several weeks from an aqueous solution of the commercial compound. The mol­ecule crystallizes in space group P\overline 1 and there are two independent 6-methyl-2-pyridone (Hmhp) mol­ecules in the asymmetric unit, together with ten mol­ecules of water.
