Mit Hilfe von 6 und 7 wird gezeigt, daß sich die Pyridiniumverbindungen 1 und 2 beider Decker‐Oxidation grundsätzlich unterschiedlich verhalten. 2‐Alkylsubstituenten werden dabei fast ausschließlich als Carbonsäuren, 2‐α‐Hydroxyalkylsubstituenten überwiegend in Form von Aldehyden abgespalten. In beiden Fällen verläuft die Ablösung der 2‐Substituenten simultan mit der Pyridonbildung. Es wird ein Reaktionsweg

The report made by Sugasawa and Ban that the oily oxidation product, produced in 66% yield, of 1-methyl-3-ethylpyridinium methosulfate consisted of 1-methyl-3-ethyl-2-pyridone only, was in error, which was caused by a cursory examination of the distillation product. The present study revealed that the oily oxidation product was really a mixture of 1-methyl-3-ethyl-2-and-6-pyridone in proportion of approximately 8 : 1. Their separation was made possible through picrates, of which the one from the 2-pyridone is freely soluble in ether, whereas the other is practically insoluble in cold ether. By using the oxidation agent in a certain excess, the yield of the product attained as high as 84% of the theoretical.
1,8-naphthyridinone compounds as modulators of an adenosine receptor are provided. The compounds may find use as therapeutic agents for the treatment of diseases mediated through a G-protein-coupled receptor signaling pathway and may find particular use in oncology.
