Beiträge zur Kenntnis der Cumarine. 2. Mitt.: Die Darstellung von Aminocumarinen

Abstract: Untersuchungen der letzten Jahrzehnte haben gezeigt, da13 eine Reihe natiirlicher und synthetischer Cumarine eine beachtliche physiologische Aktivitilt entwickelt. Fur die therapeutische Anwendung derartiger Verbindungen steht besonders ihre Wirkung auf den Blutgerinnungsablauf im Vordergrund. Diese Entwicklung wurde durch die Entdeckung des Dicumarols [3,3'-Bis-(4-hydroxycumarinyl)-methan] eingeleitet. Campbell und Link') hatten das Dicumarol aus verdorbenem Suakleeheu isoliert, nach dessen Aufnahme bei Rinde… Show more

“…[ 22-241. T h e compounds 3-acetamido-6-aminocoumarin (I), 3-acetamido-8-aminocoumarin (11) and the known compound 6-aminocoumarin (111) were prepared by reduction of the corresponding nitro derivatives, 3-acetamido-6-nitrocoumarin (IV) [25], 3-acetamido-8-nitrocoumarin (V) [25] and 6-nitrocoumarin (VI) [26] with sodium borohydride in the presence of 10% palladium on charcoal. This reagent is known to reduce smoothly a wide range of substituted nitrobenzenes to the corresponding amines [27].…”
