Synthesis of 5-Aroyl-2-aryl-3-hydroxypyridin-4(1H)-ones
Molbank, 2023 A two-stage synthesis of 5-aroyl-2-aryl-3-hydroxypyridin-4(1H)-ones (56–66% overall yields) was carried out by refluxing 5-aroyl-3-(benzyloxy)-2-(het)aryl-4H-pyran-4-ones with ammonium acetate in AcOH and subsequent debenzylation.

Asymmetric Homogeneous Hydrogenation of 2-Pyridones [PDF]
Synlett, 2015 An asymmetric homogeneous hydrogenation of 2(1H)-pyridones has been developed, using a ruthenium complex bearing two chiral N-heterocyclic carbene (NHC) ligands. To the best of our knowledge, the presented reaction is the first example of a homogeneous asymmetric conversion of 2-pyridones into the corresponding enantioenriched 2-piperidones.

Enantiopure Chiral Crystals: A Powerful Tool for Absolute Asymmetric Synthesis
Asian Journal of Organic Chemistry, EarlyView.This review covers absolute asymmetric syntheses, which allow the preparation of enantiomerically enriched chiral compounds from achiral precursors. By exploiting the crystallization of certain compounds as a conglomerate, enantiopure chiral crystals are spontaneously obtained.

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

Dichlorido[1-(1,10-phenanthrolin-2-yl)-2-pyridone]cadmium(II)
Acta Crystallographica Section E, 2008 In the title mononuclear complex, [CdCl2(C17H11N3O)], the CdII ion assumes a distorted trigonal–bipyramidal coordination geometry. The pyridone plane is twisted out of the 1,10-phenanthroline mean plane by 43.8 (3)°.
