Notiz zur chemischen Reaktivitaet von hydroxylierten Pyridinen

Ueber mehrere Schritte werden Maltol in 3,4-Dimethoxy-2-methylpyridin (2b) und Kojisaeure in 3-Brom-4-hydroxy-5-methoxypyridin ueberfuehrt.Die Bromierung von 3,3'-Dihydroxy-2,2'-bipyridin (6) liefert ein Gemisch von Monobrom-, Dibrom-, Tribrom- und Tetrabromverbindungen 7a bis 7g, bei denen die 6-Bromderivate vorherrschen.Aehnliche Substitutionsmuster werden bei der Nitrierung von 6 erhalten, wobei die Verbindungen 7h - 7j erhalten werden.Ausgehend von 2-Iod-3-methoxypyridin (8) lassen sich die Substitutionsprodukte 10 bis 15 darstellen.Als besonders interessant erweist sich 3-Methoxy-2-iod-6-nitropyridin (11), das sich zu dem 3,3',6,6'-Tetrahydroxy-2,2'-bipyridin (16d) umwandeln laesst, einen Isomeren des Naturstoffs Orellin.

Synthetic Uses of the Sequential Ring Positional Reactivity in Pyridin-3-ol and Derivatives

A series of ring-substituted pyridin-3-ols has been prepared.The key to the scheme is the introduction of a bromo group to a specific ring position as a temporary blocking agent.As well as hydrogenolysis of the bromo function, nucleophilic displacement has also been investigated.
