Die Acylierung von 4‐Pyridon [PDF]
Chemische Berichte, 1980 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.

Transacylierungen mit Acylderivaten des 4‐Pyridons [PDF]
Chemische Berichte, 1980 AbstractMit N‐Acyl‐4‐pyridonen (2a, b) sowie mit 4‐(Benzoyloxy)pyridin (3a) werden in Methylenchlorid oder Chloroform aliphatische und aromatische Amine sowie Thiole glatt zu den Amiden (4 – 6) und Thioestern (7, 8) acyliert. Primäre und sekundäre Alkohole reagieren langsamer, tert‐Butylalkohol nur noch mit 3a unter Basenkatalyse sowie mit den ...

Tautomerism of 4-Pyridones [PDF]
Bulletin of the Chemical Society of Japan, 1977 Abstract The tautomeric constants, Kt, of several 4-pyridones were determined by measurement of pKa values. For 2-substituted 5-methoxy-4-pyridones, the Kt values were correlated to the substituent constants σ, the equation logkt=2.98+2.93σm−6.18σo being obtained.

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 ...
