Lithiation of 1-methyl-2-pyridone takes place mainly at the methyl group which then leads to a dimer (11) by addition to a second mol equivalent of pyridone at C-6. Lithiation of 1-methyl-4-pyridone takes place cleanly and efficiently at C-2; this lithio derivative gave a dimer (13) with a second mol equivalent of the pyridone and reacted with a ...

Electroorganic Oxidation of Pyridones
ECS Meeting Abstracts, 2018Electroorganic synthesis can be utilized as a green alternative in complex organic synthesis reactions for pharmaceutical compounds, mitigating or eliminating complex stoichiometric oxidants during organic synthesis. An electrochemical oxidation reaction can make a synthetic transformation more cost effective and more efficient when compared to ...

Chlorosulfonation of 2-pyridones
Chemistry of Heterocyclic Compounds, 1974Chlorosulfonlyl-substituted 2-pyridones were obtained for the first time. The ability of 2-pyridone-3-sulfonyl chlorides to undergo conversion to sulfonylides of the pyridine series by the action of bases is shown in the case of 5,6,7,8-tetrahydro-2-quinolone-3-sulfonyl chloride.

AbstractAus α‐Pyridon‐silber und 1.3‐Dijod‐propan wurde 2.3‐Dihydro‐4H‐pyrid[2.1‐b]‐oxaziniumjodid erhalten. Aus 1‐Diazo‐3‐chlor‐aceton und α‐Pyridon ließen sich 1.3‐Bis‐[2‐oxo‐1.2‐dihydro‐pyridyl‐(1)]‐aceton und N‐[3‐Chlor‐acetonyl]‐α‐pyridon gewinnen. Deren katalyt. Hydrierung führte zu den entspr.

2-Pyridon-katalysierte Esteraminolyse
2005Im Rahmen dieser Arbeit wurde die katalysierte Aminolysereaktion aktivierter Ester durch Amine in unpolaren Lösemitteln untersucht. Als Modelreaktion diente dabei die n-Butylaminolyse von p-Nitrophenylacetat, die mit Hilfe von 1H-NMR-Messungen in CDCl3 spektroskopisch verfolgt wurde. Als Katalysatoren dienten alkylsubstituierte 3-Cyano-2-pyridone.
