Abstract
In the reaction of 5-chloroanthra[1,9-cd]-6-isoxazolone with pyridine bases the chlorine atom is substituted to give the corresponding pyridinium salts. The pyridine ring of the synthesized anthra[1,9-cd]isoxazol-6-one-5-pyridinium chloride was cleaved by the Zincke method. The reduction of the cleavage product, viz., N-(anthra[1′,9′-cd]isoxazol-6-on-5-yl)-5-amino-2,4-pentadienal, under various conditions was investigated.
