Continuous flow synthesis of some 6- and 1,6-substituted 3-cyano-4-methyl-2-pyridones [PDF]
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 ...

Antimalarial 4(1H)-pyridones bind to the Qisite of cytochromebc1 [PDF]
Cytochrome bc1 is a proven drug target in the prevention and treatment of malaria. The rise in drug-resistant strains of Plasmodium falciparum, the organism responsible for malaria, has generated a global effort in designing new classes of drugs. Much of

Die Acylierung von 4‐Pyridon [PDF]
AbstractBei der Acylierung von 4‐Pyridon (1) mit aliphatischen Carbonsäure‐anhydriden und ‐chloriden oder freien Säuren in Gegenwart von Dicyclohexylcarbodiimid erhält man ausschließlich N‐Acyl‐4‐pyridone (5). Auch bei der Umsetzung von 1 mit ortho‐substituierten Benzoesäurederivaten sind nur N‐Acylierungsprodukte 8 isolierbar.

Diversity-oriented functionalization of 2-pyridones and uracils
Diversity-oriented synthesis of 2-pyridone and uracil derivatives is in urgent need in medicinal chemistry as they are useful pharmacophores. Here the authors show that palladium/norbornene cooperative catalysis enabled dual-functionalization of ...
