Summary
The title compounds were prepared via intermediates resulting from reactions of 3-formyl-4-hydroxycoumarin (1) witho-phenylenediamine,o-aminophenol, ando-aminothiophenol, respectively. Intramolecular ring closures were effected between the free hydroxy and amino or thiol groups.
Zusammenfassung
Die Titelsubstanzen werden über Zwischenverbindungen erhalten, die aus der Reaktion von 3-Formyl-4-hydroxycoumarin (1) mito-Phenylendiamin,o-Aminophenol undo-Aminothiophenol enstehen. Der Ringschluß erfolgt über die freie Hydroxylgruppe und der Amino- bzw. Thiolgruppe.
