New functionalisation chemistry of 2- and 4-pyridones and related heterocycles [PDF]
, 2016 New methodology for the synthesis of several 4H-pyrido[1,2-a]pyrimidin-4-ones has been developed from commercially available 2-aminopyridines and β-oxo esters catalysed by Montmorillonite under solvent-free conditions in good yields. This methodology was

The Ring Transformation of 3-Methyl-5-nitropyrimidin-4(3H)-one
Molecules, 2003 3-Methyl-5-nitropyrimidin-4(3H)-one readily reacts with carbonyl compounds to produce three kinds of ring transformations. The nitropyrimidinone behaves as the synthetic equivalent of activated diformylamine affording 3,5-difunctionalized 4-pyridones, 4 ...

Continuous flow synthesis of some 6- and 1,6-substituted 3-cyano-4-methyl-2-pyridones [PDF]
Journal of the Serbian Chemical Society, 2019 In this study, six 6- and 1,6-substituted-3-cyano-4-methyl-2-pyridones were synthesized in a continuous flow microreactor system. The syntheses were realized at room temperature and the obtained results were compared to those achieved within classical ...

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.

Ruthenium(II)-Catalyzed Remote C–H Sulfonylation of 2‑Pyridones
, 2023 Herein, a ruthenium-mediated remote C–H mono- and disulfonylation of 2-pyridones with arylsulfonyl chlorides is developed. The catalytic system consisting of a [Ru(p-cymene)Cl2]2 catalyst and KOAc additive allows 2-pyridones to undergo C3,C5 ...
